Wyvern

Thanks. Move mountains worked. It was a break in the middle of the wall.

On to the next battle...

This is the third time I've played through Avernum 3, but I can't remember how to get to Ulhioc the Troglodyte. I went through to his machine and pressed the buttons on his pedestal to line up the runes. But I can't go anywhere from there. The runes lead to a blank wall and there's no secret (or visible) door out of the rune room. Am I missing something?

I checked the Walkthrough and all it says is to walk across the runes and that Ulhioc is in the room to the north. FarSight shows a room on the other side of the wall, but I can't figure out how to get there.

What am I missing? Thanks.
