Ranks

Nomads are, as their rank name suggests: Nomadic! They live off the land and are generally much heartier and bulkier than other ranks (Besides Guardians). They have much more fur and as a result are more cold resistant. They are survivalists and live in small family units outside city limits.
Nomads also know how to go toe-to-toe with massive Aberrants, and are prone towards being travelling merchants or musicians.

With a MYO slot, you can make a Nomad instead of a Civilian, if you so choose!
