Ma'zaddha is a Khajiit thief living in Crucible, New Sheoth. He regularly gets in trouble for stealing but claims he is just trying to get his stuff back and is involved in a major conspiracy to assassinate Lady Syl, the Duchess of Dementia. If he dies his tombstone will read: "Mazaddha found that which he did not seek -- the sharp end of a blade."
Although he initially refuses to speak even after torturing by Herdir he eventually confesses after being caught meeting with Nelrene at night. He claims Nelrene is receiving orders from someone and promises to bring names. The next day Ma'zaddha will be found slain in his home but will have hidden a note from his killer that reveals Muurine as the brain behind the conspiracy.
He is a member of the ‘Duelists’ and at 8pm everyday heads to the rooftop of Sickly Bernice's Taphouse for two hours of drinking and fighting with the other members. Ma'zaddha participates in the fights taking on Muurine on Middas, Caldana on Loredas, Cutter and Ushnar on Morndas, and standing on the sidelines cheering and drinking on any other day.
