To help me help you, but really to help me.

FROM HAL:
1. A Mountain with a Door on it.
This dungeon had a bunch of orcs in it, but it looks like the halls were cut by dwarves...I didn't see any treasure and didn't feel very powerful, but just to test things out I killed an orc while keeping to the shadows. Boy the rest of the dumb orcs were scared.

2. This one had a trogolodyte carved on it.
Oh man did the place reek. I felt really powerful and just kept prestidigitating better smells, so it wasn't too bad. Place had lots of trogolodytes, which usually means they're guarding something powerful.

3. This path had a displacer beast carved into it.
I felt less powerful than in the trogolodyte caverns, but this place was unexplainably beautiful. An underground jungle of glowing trees! There was a sign written in both common and elvish: BEHOLD WYLLOW’S WOOD. HARM NOT, LEST YE BE HARM’D. So I decided head back. Probably lots of good loot there.
