Silk Rat/Silk Rat Swarm

Whether a single scrap of richly colored cloth, or banded together as a well-tailored clothing article, silk rats are devious constructs that seek to constrict and devour their prey when the time is right. At rest, they are indistinguishable from inanimate silk and can naturally fold themselves into appealing shapes or nest together in a fine imitation of any attire. Once in motion, the silk rats snap into an angular approximation of an oversized vermin, complete with remarkably sharp teeth and a lashing tail of loose threads.

Killer Outfit. In life, La Contessa loved fashion. She and her younger sisters sponsored many a seamstress and tailor in their kingdom. Whenever she was at court, the woman sported the latest fashion. Most didn’t know that La Contessa directly consulted on the designs she wore, and even stitched together a few dresses herself.

After vampires destroyed everything she held dear, the alchemist’s first creation was the silk rats. These constructs could hide in plain sight ranging from a fine cloak she wore, to a pocket square, handkerchief, or just a pile of rags. Their artificial nature allowed them not only to stymie La Contessa’s undead targets, but devour their lesser minions as well. Her greatest accomplishment was slowly infiltrating dozens of silk rats into a vampire’s manor to replace all the curtains. Then, when the time was right, the constructs let all the sunlight in.
