Ubayid (pronounced oo-BAI-yeed) is a Chammuran employed by Lady Zenadia doa Attaneh. He is the lady's armsmaster and is a skilled swordsman. It is implied by the mutabir that the rumors of murder in Lady Zenadia's house existed even before she took up with the Vipers. Before and during 1039 KF, he and the Mute commit a series of murders in Zenadia's name, including those of the spies that the mutabir has placed in the lady's house. He only appears in Street Magic, where he is a minor character.
