Humans are... well- human. Weak and pathetic. They are
born white on the grey scale, and collect gray through
out their lives, usually dying with a black status.
Humans are innately 'evil' so they rarely stay white.
They are born with a very small amount of life force,
and collect mass amounts of it up until their teenage
years, where it begins to trickle away gradually. They
die when they have expended all of their life force.
Humans who learn to use supernatural powers exhaust
their life force faster than those who don't, and
usually die young.
