Tengus are a race of avian humanoids that resemble crows or ravens, and often bear much of the same stigma. Though they frequently choose to live among other races in densely populated cities, their society is tight and closed, and they rarely allow others to see its inner workings. Tengus often band together in small groups to create roosts in vacant warehouses or condemned buildings, and these raucous gathering places are generally assumed to be thieves' guilds by outsiders-an assumption that's correct roughly half the time.
