Taharak was once a powerful warrior among the drow of Maerimydra in life, before rising as a ghost after his death.
Taharak cut an impressive figure in his full plate armor, even more so when wearing his leering skull helm and astride his nightmare steed. In battle, Taharak wielded a spiked chain.
Before his death, Taharak fought for Lolth. However, after dying he took up the cause of Kiaransalee, rising anew as a deadly ghostly champion.
During Lolth's Silence in Maerimydra, the rising cult of Kiaransalee there put him to work as a scout, collecting the corpses of the fallen and bringing them back to Castle Maerimydra for reanimation by Irae T'sarran's servants.
