This cabal of slavers came to Castle Whiterock after being nearly wiped out in the south.
They have since learned the merits of operating in secrecy, and Ikenvar, their leader, has taken steps to disguise his operation as monks of the Dawning Sun, going so far as to insert an agent in Cillamar in the guise of the undertaker.
The slavers conduct a brisk business with the Thane of Narborg through the orcs of the White Talon.
Ikenvar is desperate to not have his organization threatened, but if subterfuge fails, he will scarcely hesitate to use force.
Update: This band of Slavers are deceased due to the actions of the adventuring party.
