Nimmies were one of the first sapient non-human races created, and are one of the most widespread – While most common in the Americas, they can be found on every continent.
...mind, they’d probably be even more common if most other peoples didn’t hate them with a passion and frequently attempt to exterminate them.
Physically, Nimmies are fifteen to twenty five pound rats with hand-like forefeet and somewhat larger skulls. They’re sapient, although their IQ tends to average at about 70 when compared to humans.
They’re giant, talking rats. Clever giant talking rats, but still dim by human standards. At best, they’re slightly flakey allies and fellow citizens. At worst, they’re incredibly destructive and potentially dangerous pests.
...yeah, it’s more complicated than that, but ’s how most other sapients view them.
