Bracchus

Bracchus is a tall satyr with black fur who had antler horns instead of the goat horns of normal satyrs. He is the current leader of the Van Wilders.

Codex
During the party of 1 May 1491, the adventurers learned that Bracchus was what is known as a Stag Knight, an elite soldier of the Unseelie Court who led similarly black-furred satyrs who slew inhabitants in the Feywild.
