Auriel's Bow (Morrowind)

Telvanni Councillor Therana will talk to you about this bow, which she says "smells faintly of Ash Yams." She says the "smell" is strongest in Ghostgate near Ralyn Othravel. Ralyn can be found in the Tower of Dawn and is indeed carrying the bow, though you'll have to kill or pickpocket him to get it.
