And now begins the owning. If I had known it would be this much like a D&D game I would have responded earlier and also asked for the statistics of the world to be posted so that we (the readers) could run around and play in it. And maybe help expand the world a bit.
Obviously the Red Reyn are human counterparts(bonus feat, weapon improvisation, Favored class Fighter/Wizard), Grey Reyn are good at climbing and moving about, with a touch of low light vision(+STR/WIS, -CON, favored class Druid/Sorcerer), Snow Reyn are good diplomancers and crafters(+DEX/CHA, -WIS, Scent, favored class Bard/Paladin), Fens are short, but great of hearing and oddly resilient(+CON/INT, -STR, Small size, favored class Monk/Rogue).
Needs more races for a traditional fantasy game, though, that's only 4.
Spell lists would be oriented towards a more light-hearted game. Why cast Baleful Polymorph when you can have Cutesy Feralization instead?
