Got room for one more? Also, would you be allowing characters from other universes like a D&D-styled Half-Elf into the setting? Also, is there any chance we'd get to interact with any of the characters from the show? Not that I'm expecting to play as them or have them become the focus, but it'd be interesting to have cameos or missions where we'd get to work with them for a bit.

There is certainly room for more.  As for your questions from the interest thread: No they can't be a character from other universe, but there are quite a few races that have similar looks to elves such as the Gelboians, could even be a half-elfish type race if you set up the backstory correctly.  The setting is in its own universe so there are no canon characters from the show, as of now I have no plans of any multi-verse shenanigans that could bring in any canon characters.  So in sort almost certainly not.
