Cabal's Ruin

One of The Vestiges of Divergance
A magic-devouring cloak once used by an assassin to eliminate the unscrupulous Den of Druja. interesting, this would make sense, given the headmaster in Anky alluding to the fact that the Den of Druja was lead (or at least heavily influenced by) a former member of his association, assumingly, a magic user. So, anti-magic cloak definitely tracks.
It is now worn by a merchant-warrior with a missing eye in the walls of Ank'harel This warrior was Mistress Asharu, who was (ostensibly) killed by Doctor Anna Ripley
