Mire of the Damned

Castle Darkmoor is a three-switch / blue-cube puzzle. Pull the first lever after the south sign; cross the Jump gap to the second sign and pull its switch to arm a second cube; then cast Telekinesis on the blue cube in the large room (“The way has been cleared”) to open the path to Memory Crystal Delta in the northwest alcove. With Delta in hand, turn to the nearby blue cube, click the wall plaque, then click the now-red cube (or double-click the hanging column) to teleport to the Book of Liches room. Click the book to destroy it for Terry Ros’s quest. The three corpses there drop excellent loot (e.g. Ultimate boots), but looting them is a heavy reputation hit — skip it if you are protecting Saintly status. Click the red cube again to teleport back out.

Some doors here are opened by attributes, not keys: the door past the first big room wants a caster with high Intellect to open it. The Cell Key sits in a chest guarded by higher-ranked dwarves at the end of the southern path. Carry it to the cell in the first room on the right near the back of the mine and use it on the cell door; the imprisoned dwarf inside hands you Snergle’s Room (Chambers) Key — the only thing you actually need from this dungeon. (The Orders From Snergle scroll you can find is useless.)
