Meesha is the sister of Purrow, and together they form the Aisha theives, a duo wanted for theft from the chocolate factory at the annual chocolate ball. Meesha and Purrow hideout in the sewers, though Meesha has a tendency to get caught.
Her relationship with the Thieves Guild is unknown. Purrow holds a membership pendant, but the Guild's Neopedia entry implies the pair are not members.
