Fenweed
Template:Flora & Fauna Fenweed is a poisonous plant that grows in the Forests of Hell on Threnody.[1]
The primary property of fenweed is to induce extreme headaches, drowsiness, dizziness, sleepiness, and a cloudy-head.[1] Fenweed has a very light taste, so it can easily be masked by the flavor of food or beer.
Fenweed has to be mixed into a paste to be used.[1] A full dose of fenweed in a man's meal or drink is enough to put him straight to sleep. A half dose will leave him mostly unaffected for a while, but after a time he will fall asleep, although not so deeply that he could not be roused.
The name of fenweed implies that it can be found in swamps.
Silence Montane has her daughter, William Ann, give Chesterton Divide and the four men of his gang a half dose of fenweed in their beer, so that she can later kill them in their sleep.[1]
