Jerrus Bigelow

Jerrus Bigelow was the leader of the Subtle Hand. He made a pact with Glaucon and used his dark gifts to rise to the top of the Subtle Hand. Jerrus was killed by the Bucket Fillers, who tracked him down after Butttoucher found records of necromantic artifacts being traded more frequently within the Subtle Hand.

Pre-Campaign
Not much is known about Jerrus's early life, but it was known that he was crippled for a long time before he gained his pact with Glaucon. He used this power to completely heal himself and created a global empire of crime.

The Ringbearer Chronicles
Jerrus was eventually tracked down by Butttoucher for the sale of numerous necromantic artifacts. When he became aware of this, Jerrus sent a strike team out to find and kill Butttoucher and any of his associates. This failed miserably, and the Bucket Fillers eventually found their way to Jerrus, who was hiding in his mansion located in a demiplane in a mirror.

Death
Jerrus fought off the Bucket Fillers for a while, but he was eventually killed by a crossbow bolt to the chest by Butttoucher himself. As he died, Jerrus begged to be spared Glaucon's hunger. However, it was too late, and Glaucon took control of his corpse.
