ToME: the Tales of Maj'Eyal

On the first level of the maze with the alternate layout, the placement of threee crevices has surrounded a small open area (an L, 2 x 3 squares) with walls. I can see a gold chest in that area, but the walls are all non-diggable. I will try repeated teleports to get to it, but I think the easy fix is for the application of crevices to the maze layout to make the walls near the crevice diggable

makes sense. something damaged them, so maybe they aren't protected by the enchantment any more.
