Just decoration! No need to enter it! Sorry, I might remove it if it’s confusing! Just need to head back from where you came and find another way forward (southern most portion of the map)
I´m stuck there too, I already went all the way back to the main entrance where you pull the chain but I can't get back any further or find the way forward from there. is there a walkthrough or anything available by chance?
You don’t need to go back that far! I meant that you needed to leave where you entered the room to rescue Jamar. The map there where you entered, go as far south as you can. It’s a large map. Jamar’s room is an optional puzzle room and not required to enter at all.
