Mereth Akure

Mereth Akure is the former lead magister of The Black Hand and the mage responsible for the killing of the Inquisitor in Pessa. The Clive Five attempted to raid her house to steal a ring for Father Bound, which led to the capture of Gideon and Vondal, leading to the death of the latter.

Later, the party briefly encountered Mereth Akure as she returned from a strange underwater temple off Sandshore bay. In the resulting chaos, she teleported away before a beam of divine energy destroyed her ship, after bagging a black crystal of some kind.

When the party arrived at Orristas, The Clive Five were introduced to Master Emon and Ethemyr, his quiet apprentice. After freeing Orristas from the Doppelganger invasion, it was revealed that Mereth Akure was in fact Ethemyr, and was also potentially one of a number of clones. It isn't quite clear whether the Mereth Akure that worked for Caya Calco and The Black Hand was the same one.
