Nezumi

A non-native race brought to Tarana by the omniversal nexus, the nezumi, or ratfolk, are a race of white-furred rat-like humanoids that dwell in the swamps of the continent of Wujan, and in small groups around cities. Physically, the nezumi tend to be fragile compared to most other races, while making up for this in cunning and swiftness.

Cunning Mercenaries

The nezumi often find lives for themselves as thieves, ninja, or samurai, working for the highest bidder willing to put up with their underhanded tactics. Nezumi are known for their physical weakness, but their agility makes a nezumi mercenary priced for tasks focused on stealth, infiltration, or assassination. Those going into combat against nezumi are often completely unaware of it.
