I came up with a variety of humanoid 'species' that evolved based on their physical environments. Not sure if I still have notes on any of them, but when the time comes to write the series, the differences between the species will be a big part of the conflict. The story will be a precursor to Pete Drake's Omni tale. I love three of the main characters, although I can only remember the intended name of the protagonist now: Orlian.
Wow, this makes me want to work on that project now!
