#Dungeon23 Tomb of the Vampire Queen, Level 4, Room 19

 The secret door, really just a hidden one, is to the right from the perspective of heading toward Room 20. There are a few stones to move (combined strength of 20 required, up to three characters) the biggest obstacle is the dark.

This appears to be the Grimlock's larder. In here are four Trolls. They are tied up and their limbs have been hacked off.  The grimlocks have captured them and are keeping them near death as a regenerating food source.  Their limbs are growing back at odd angles and lots of mutations.

Each troll only has 1d4 HP each. They can be easily killed but only give 10 XP each.

There are a few magic items here too. One is a sword +1/+3 vs. trolls. It glows in the present of trolls. When the trolls are dead the glow will stop.  The trolls were afraid of it, and the grimlocks hated the light.

There is a wand of magic missiles here as well. It has 2d6+4 charges remaining.
