Stuck at End of Chapter 5 - Help

[RTS Luke]

Been using a relic guide here is where I am:

SA28) Once you're back inside the room with the four statues in the middle and one blue one on the floor. Use Telekinesis to pick up the blue statue and place it on the empty pedestal to your left.

SUPERIOR NAGA SILKSWORD - In the hole revealed for SA28

SA29) From SA28. Instead of making a left and returning to Leanna. Make a right and head back to where you see the Cyclops. You can use the lever now to get back to where you fought a ton of Goblins. Go upstairs and use the Spider Key on the door in the middle of left wall.

RING OF PROTECTION - In the SA29 room. On top of the coffin.

SA30 & 31) Now cross the bridge again and use the Spider Key on the doors along the right wall.

---> So instead of turning left to return to Leanna after defeating aratrok, I headed to get Secret Area 30 & 31. However, the gate I came through from the Cyclops area the lever was on the side coming in and has now closed and the gate heading up to the Upper Temple (a blue sign) is also closed, essentially trapping me in this area, anyone have any suggestions on how to get out or encountered this before?

Unfortunately I do not have any earlier saves and am pretty much trapped here.
