Yep the Felis are a parody of mithra, and female mmo characters in general with ridiculously skimpy outfits and other quirks. The Territh are a parody of galka, ogres from EQ and the other large MMO races no one usually plays with the exception of stat--CENSORED- and people playing them because no one else plays them. The half-fae are also an EQ parody of their fae. The reason they are only half in this world, is that I'm using a more traditional translation of what a pure fae is, an ethereal being not of the world. They mated with humans and elves and poof, you get half-fae. I may add something dwarf/taru-ish later suddenly appearing in the world with the first "expansion."
To start things off on a fun note, the first few story comics are actually based on Koge before the actual quest starts so his character comes into play right off the bat, followed by R'lora, the lead character.
