Kain Darkwind's Savage Tide
Arrak Beedle is Kat’s uncle by marriage. He is a powerful spellcaster and developed an obsession with Fiend’s Embrace, which he contracted Heinrick Gilantheril to recover for him. He subsequently vanished, allowing the cloak to come into possession of his son, and later his niece Katrina.
A simulacrum of Arakk appeared and attempted to recover the cloak from Katrina and the Steel Wyverns. Though overcome the simulacrum left behind the Deck of Many Things, which resulted in Katrina and Heinrick’s banishment to the void.
