OK, so I'm in the place in the swamp where the monk tells me to 'save the lamp' from Nehria. So I went south from there and killed the crazy woman that looks like Medusa, and stepped on the two buttons, but nothing happened. It looks like maybe one of the tombs is supposed to move, because on the map it shows up as a hole, but I don't know. Where am I supposed to go to save the lamp? Do I have to leave this place and it happens later?
Thanks,
Greg
