They are based off the Gatorfolk from blackmoor, they essentially put it as a grand war of evolution between them and the Froglins, a race spawned from frogs and genetic manipulation. I've been working on Blackmoor pathfinder conversions and though 'heck maybe a breed of gatorfolk who are bred for what they deem the War of Evolution' might work, I think I might have some notes on a few other ideas that could be used instead.
If it isnt appropriate I'll try to work something different.
