Today I received a copy of the Stronghold Zine. On the back of the envelope Boric drew a gorgeous little map. I love it! What follows is a wee dungeon description to "flesh it out" so to speak.
The Skin Lab
The crafting of flesh golems is a rather grim affair, but the citizens of Drainpipe don't mind too much provided none of their relatives end up being used for spare parts. In this secluded work space, a powerful wizard (her identity remains a secret) crafts flesh golems.
Once completed, the golem lives in the hidden caves behind the lab until a buyer can be found. Flesh golems are not cheap, so finding a buyer with adequate coin can take a while. The most recent sale was to Colin Crumb, a purveyor of extra-planar trash.
The lab is full of all kinds of jars, surgical tools, sutures, arcane manuals, and so on. Most of the work occurs on the table in the lower left corner of the map. Once the flesh golem is sewn together, it is lowered into the pool at the upper right of the map. The pool is full of electric eels that shock the golem into semi-consciousness.
The materials within the lab are worth 5,000 gp but stealing them is a death sentence. The wizard who owns the lab could locate the pilfered goods through magical means. Once located, the thieves would no doubt end up as spare parts for the next golem.
Save for the flesh golem (link to stats) in the caves, the lab is unguarded. After a few rounds of poking about, intruders will come face to face with a 7' tall Frankenstein-like monster looking to tear someone apart.
