Vorka did indeed, after the death of Butler, become slightly obssessed with power. But in a good way. Yeah.
He collected his own spellbook's might, various holy artifacts, and runespells, minor metahuman powers from Amelia Moore, the dead superhuman, and used a Basque love-charm to temporarily steal the powers of a demi-goddess known as Mercedes, who was in the Taverna. Combining these with the Gift of Ice he already stole from one of Astir's vessels, he then attacked Astir, and killed him - taking his powers, and all associated issues, in the process.
Now, immensely powerful, Vorka cast away the godly power from Mercedes, and flew away. What will he do next?!
