Ideas for alien races so far: -Bural: A cat/dog-like race that stand anywhere from 15' to 20' tall, can change between male and female forms at will, and can take on the form of a human. -Birmaru: A humanoid cat/dog-like race who have a berzerker form (I'm still trying to figure out what it will look like). -Draken (a.k.a. [i]Forerunner[/i]): A humanoid dragonic race who's technology is thousands of years ahead of the Covenant.
