This will take a while and will require a solid understanding of how the game works.
Pick up earth, water, lava or plants with , and drop with . If you hold and at the same time everything you have absorbed will be dropped in one go
Sometimes you can stop a river completely, to do this pick up some earth or lava and drop it on the source of the river. This won't always work as sometimes the earth is simply washed away after a time.
As soon as enough land is covered for the vegetation-gauge to say 100% and you have all the relics you can leave. To leave a level send your people to the passage, a stone face, and hit while hovering above it.
Activate powers using the D-pad and deactivate them by hitting the same key on the D-pad.
The following is a guide for the main story missions, please refer to this THREAD for the challenges.
Story Mode Guide:
Level 0: The Breath
Nothing to do but create the breath by holding and then to guide your people to the passage. Use to absorb earth and to drop it in the water to help your people cross it. Once they reach the passage hit on the passage to complete the level.
Level 1: The Ritual
Simply connect the land and block the waterfall. While waiting for the land to be covered you should grab the relic on the mountain next to the second totem, simply send someone over there and when (s)he is there hit . When you grabbed it and the vegetationgauge says 100% go through the passage to finish the level.
Level 2: The Roar Of The Sea
Bring the people to the first totem to start the village. You will then get a warning about a tsunami. So bring a man to the knowledge of Repel Water by first connecting the land and then redirecting the river, which blocks your path, near its source.
As soon as your shaman picked up the knowledge he will go back to the village and will spread it. The first tsunami will be repelled, but another will come within 8 minutes, in which you must create a village near the second totem and you must spread the knowledge of repel water to that village as well, otherwise it will be destroyed. So guide your villagers to the totem and create a village, best way to do this is to grab a large amount of land and create a dam, so this river will get redirected as well, preferably in a way so that it streams right of the second totem.
Connect the land of the second totem to the last bit of land containing the passage, send your people over there and just wait for the vegetation to spread and leave through the passage.
Level 3: The First Power
After building the village and seeing the tsunami strike, go near the volcano for the knowledge of Repel Water and bring it back to the first village. While waiting for the second tsunami strike keep picking up lava and throwing it on the wall behind the second totem. Keep doing this until after the third tsunami, after which you will see that no water will pass the wall in such a way that it will destroy a village (if it does keep absorbing and dropping lava). When it's safe, build your second village.
Go back to picking up and dropping lava to redirect the river, the one that begins next to the volcano, so that it flows towards your first totem. Start picking up the earth near the volcano, which respawns, and dropping it over the stone so that vegetation can grow there. Now send your men to the third totem and hit to use the Jellify Water power and move aside the water between the second and third totem so that your men can cross.
After the village is created, keep picking up land and covering stone until you have a 100% vegetation after which you can leave, unless you want the Krakatau achievement now.
If you do want the Krakatau achievement now you can keep on absorbing lava and dropping it somewhere, not on your village ofcourse. I don't know how much lava you need to pick up.
Level 4: The Thousand Sources
Pick up land and drop it on the source of the stream, which is close to your people, then send them to the first totem and build a village. After that grab the knowledge of Repel Water and head up to the second totem, which requires you to drop land on the cliff so that your people can run up.
To the right of your second totem there will be be sources of water hidden beneath the land, so remove the land and use it to build a dam so the water doesn't get the chance to drown any villages (in case the knowledge has not spread yet). Keep picking up land right of the second totem to unearth more sources and drop that land on the dead vegetation, that men cannot cross, near the third totem to allow them to cross it. Water can also be used to remove the dead vegetation. When you can send men to the third totem do so, if they ask for help hit to evaporate the water and allow passage.
By the time that you created the third village you probably have 100% vegetation. Now you should pick up the relic to the left of your first village. It will be on a hill so you will probably have to throw earth on the hill so that he can climb up.
After you picked up the relic and have 100% vegetation send your people to the passage and use Evaporate to give passage if needed, if your people did not reach the passage by the time Evaporate ended, use Jellify water immediatly to hold of the water. As soon as your people have left hit on the passage to leave.
Level 5: Wildfires
Send the men to the first totem to build a village. Then send them to the second one, which you should replace, as told, after building. Send someone to pick up the relic left of the new location of the second village and replace your first village next to your second village. Place the water trees away from the villages to make sure you are safe of dangers.
Go build a village at the third totem, which you should place next to the other villages. Now build the fourth village and quickly relocate the fire trees so that they don't burn this village.
Now wait for a 100% vegetation, for which you might want to replace some villages. After you have 100% vegetation you can leave unless you want the Amazon achievement now. As soon as you leave the Hell achievement will unlock.
If you do want the Amazon achievement now, simply keep uprooting a water tree with and replanting it with until it pops.
Level 6: Waves
Build a village at the first totem. Then build one near the Jellify Water totem and grab the relic near the second totem. Then grab the knowledge of Repel Water above the second totem.
You will probably have noticed that the land, and the water, between the knowledge of Repel Water and the third totem, Amplify The Breach, keeps shifting. So while collecting the knowledge you should use Jellify Water. Once the knowledge is spread build a village near the third totem and use Jellify Water to keep it safe.
Then you should build a village near the fourth totem, Put Out Fire, and here you should use Jellify Water as well to keep the village safe until they know how Repel Water.
When everyone knows how to repel water, grab an explosive tree and place it near the wall, then grab a fire tree and place it on the explosive tree to destroy the wall. Keep doing this until you can send your people through.
Leave as soon as you have 100% vegetation.
Level 7: Hightides
Send men to build a vilage at the second totem, Jellify Water, and use Amplify The Breath to hold back the water to help your people make it. Wait for it to be build and to have gained the knowledge of Repel Water. Then let the knowledge spread to the first village.
(Saving right now is recomended!) Now grab the fire trees near the third totem, Engulf All, and place them somewhere safe, so they burn nothing. Surround the third totem with earth so that the water is held away, this requires almost all the earth that you have so far. When no water can go near the third totem start building a village there, when they know how to repel water you can take away the earth and place it all in another opening to the right.
(Saving again is recomended!) Then, when the water withdraws, send the men to the fourth totem, Infinite Earth, and start building. The water will come back so use Jellify Water to hold it back and if needed use Engulf All to help in your defences as well. Eventually this village has gained the knowledge of Repel Water as well, so you can start covering the world with earth. When you have 100% vegetation, leave this place.
Level 8: The Tears Of Stone
Build a village at the closest totem and then gather lava to block the right stream, near the source, so you can collect the knowledge of Repel Lava. Then block the left stream so you can build a village at the Put Out Fire totem. When you have two villages, both with the knowledge, block the right stream at the source of the lavariver, so that the lava will stream on the left. Then when the volcano has erupted go build the village on the right and spread the knowledge, afterwards gather the knowledge of Repel Water. While waiting for the volcano to erupt grab the relic that you will find at the top of the volcano.
When the villages have Repel Water and Repel Lava you can start going for the fourth, Engulf All. The fourth is covered in water, to the right of the volcano. So first you should use Jellify Water and then with the help op Amplify The Breath gather all to water away from the source, which is above the totem, and then block it with earth. Now build the village and you'll see that water comes pouring out, making the volcano 'cool down' and it will help cover the stone with earth, so just wait until you have 100% vegetation and then leave.
Level 9: The Raging Earth
Build your village near the Amplify The Breath totem, and use the earth around this totem to block the first three water rivers and first branch of the fourth river so you can easily send someone to pick up Repel Lava.
After your village knows how to repel lava, you want to use the lava to make a wall in such a way that all the lava streams towards your village, this way you can easily grab the Repel Water and build a village near the Infinite Earth totem later. After grabbing the Repel Water wait for the tsunami to strike, if there is one approaching in ~25 seconds, and build a village near the Jellify Water totem and wait for the knowledge to spread. If the tsunami broke through the little dam you build earlier, rebuild it first.
Now build a village near the totem Engulf All, and again wait for the knowledge to spread. As it has spread send a man to collect the relic just to the right of this village. The last thing to do is claim the last village, use lava to rebuild the wall to make sure it streams straight for your first village, that way your men can go past without harm. Use earth to help them get over the wall if needed.
Now just use Infinite Earth to help cover the world with vegetation and leave once you have 100%.
Level 10: Emergence
Start by making roads and creating and clearing the islands for all the totems. Then create some roads to the knowledge of Repel Water and Repel Lava. And as soon as you finished making all the islands and roads start creating a village near the Infinite Earth totem, and then grab the Repel Water. Create the other villages and grab the Repel Lava near the Jellify Water totem.
Now all that is left is to grab the relic, which you will find between the spawn point and the Amplify The Breath totem right across the volcano (it's quite far away from the shore). Make a road over there and collect it.
Now just keep expanding islands until you have 100% vegetation
Level 11: Movements
As soon as it rains use Evaporate!
Build walls with lava and Infinite Earth.
Build your first village near the Evaporate totem. After sending your men, bring as many explosive trees as you can and set them in the lake next to your future village. As your men are running towards the totem, keep them alive and use the lava to build a wall between the future village and the source of the lava. After that send men to collect Repel Lava. Use Evaporate to remove all the water so your men can pick it up and deliver it. While waiting create a village near Infinite Earth and when it is done, move it next to your first village, if you weren't fast enough you can use Infinite Earth to raise it so it doesn't flood. Then use Evaporate to remove the water. Now keep building a wall with lava around your two villages while waiting for the third rain and eruption. After which you should build a wall around Jellify Water, until it is about as high as the previous, and then create a village. Keep on building the walls and use Infinite Earth to help the shaman carry Repel Lava to the Jellify Water village. When its over rebuild the wall as much as possible and prepare for rain. Now wait for the lava to withdraw a bit, which will take a while as you might not want to have the risk of the rain drowning your villages.
After that build a wall around the last totem, and when it is as high as the previous walls build a village. Spam Infinite Earth on the ground to get 100% vegetation, not to close to the lava ofcourse, and leave. As soon as you leave the End Of Our Journey achievement will unlock.
Note: If you always use Evaporate when it rains it is quite possible to not lose a village here.
I lost one village, because I ended Evaporate BEFORE the rain stopped, this made one of my villages drown. So don't I would suggest not to disable Evaporate before the rain ends.
A second solution by Maka can be found HERE.
Level 12: Origins
Build your totem with . Then use the D-pad to use your powers to create earth, water, lava and plants. Just use earth to make some place for your totems and once there is enough place a totem with .
Either experiment and do it as you wish or keep on following the guide:
Keep your villages together and position them in a square and put them high . Now just make enough earth and cover it with plants. When you reach 50% you will unlock the last memory and thus unlocking the Memories Found achievement, if all other memories have been found. And when you reach 100% you unlock the Green Thumbs achievement and the ability to place the sanctuary.
Warning: Starting the creation of the sanctuary is irreversible and can be terrible as it is quite random, since it depends on the land you build and how far you placed the sanctuary away from your village(s).
Once your ready place the sanctuary as close to one of the villages as possible and make your people storm it and spam . Once your people passed through the Sanctuary achievement will be unlocked, if you lost less then 5 villages then the Safe Journey achievement will pop as well.
