Mysterious Drow in Mithral Plate

Not much is known about this drow. He has been seen across western Akellon, usually just before, during, or after monster outbreaks in an area. He wears a suit of mithral full plate with an unusual symbol etched onto the shield, and is said to ride a black-winged steed that Miron Steelsprocket suspects is a corrupted pegasus. He may be connected to Cal'tel.
