After waking up the sleaping guy ( I forget his name ) I can't exit the temple - when I push the button that previosly teleported me acros the pit to the exit area, I now just fall down the pit ! Is there another exit ? and if there is will, I need portal/call of home to return to the town ?

There are two exits. The front door is easy, just make sure you are standing close to the pit when you press the button. (Took me ages to figure this one)

The back exit is near to the guy you resurrected. Nearby is a wrecked room with a collapsed piller, beyond that was a locked door that has now opened and leads up to the second sea.

I'll check it out - thanks !!
