Yeah, I do it all the time.
The Noctero
A race of reclusive, bat-like creatures that have been taken in and put to work by the Industrialists.
Stulters
A race of 12 foot tall traders. Clem's village was wiped out and set aflame from a rival village attack, so he left to become a Mercenary.
Glurbbs
Glurbbs are giant mollusks that are just crossing the boundaries between animal and sentient being (like the "missing link" would be concerning us). They stalk the swamps like crocodiles, disguising themselves as rocks to avoid detection. Burtha is one of the most intelligent Glurbbs alive.
Starks.
Starks are sentient, flightless waterfowl. They are also incredibly skilled acrobats, and can leap through the trees like it's solid ground. They speak with a strong French accent.
Tapewoimz
Tapewoim skull
Tapewoimz. They may look like 40-foot long viperfish with arms, but they're actually related to birds. They live deep underground, and create vast tunnel systems, some of which were unknowingly used by the Mudokons in the creation of their temples.
They have a very laid-back lifestyle, and the group Actra and the others meet haven't moved from their home in years. Unfortunately, their tunnel is placed along the sewer system for New Rupturefarms, which is... really starting to piss them off. Why, if it wasn't for their peace-loving nature and the giant, hallucinogenic mushrooms, why they might just do something about it.
Oh, did I forget to mention the giant, hallucinogenic mushrooms? Premo stuff, man. Killer. It's like, all your troubles just... melt away, man. Then your hands start to grow and shrink in front of your eyes, and before you know it, your pupils dialate and you think you're a car. You ever read a poetry from a stoned tapewoim? Funny as hell.
