Found at the Camp in Vendrien's Valley, Shivershank (or Fuckwit, as Quiet Shiv insists) is a fresh gang boss in the Chorus. He's a former ship captain and doesn't take lightly to people challenging his right to be a gang boss.
This character has no special interactions.
The Fatebinder can interact with the Chorus warriors and take a side in the fighting, order them to cease and desist, bet on either side winning or simply walk away. Interfering does incur wrath with the Chorus. Otherwise, they will fight it among themselves and settle the situation.
Forcing them to stop their fight will incur minor Wrath with the Chorus and minor Favor with Tunon.
