A Souli is a group of cohabiting Banu who have formed an alliance centered around a specific, shared skill set. Akin to a combination of a family and a corporation, members of a Souli have been raised by the group since they were young. There is a Souli to cover every aspect of life, including medicine, item manufacturing, repair, writing, politics, religion, bureaucracy, trade, and so forth. The Souli is the single most important group in the life of a Banu.
