Qoledre Sarinaha is an ancient elf from Merdelain, possibly the leader of that house.
The Sarinaha are the slavemakers of Merdelain. Their mark is a crescent moon pierced by a downward-pointing sword. There is evidence that they have been able to enslave sorrowsworn.
Qoledre Sarinaha was the one who engaged Ebonidris, dismissing his magical sword and then wrenching the soul of Ebondeath from Idris's changed body and enslaving it into a soul cage. Her people then killed Idris in the aftermath.
