Find a skeleton chained to the wall in The Deathfist Jail, at ( -15, -10, 7 ) /waypoint -15, -10, 7 and inspect it.
You will receive 2 items, a tarnished bracelet and a dusty arrowhead necklace. These once belonged to a Green Hood, Marshal Cristof. The inscriptions confirm this. (And yes this is the same one that also shows up in the peacock club, spooky isn't it?)
