Greens: Green dragons are small, quick,
agile dragons, being about 60 feet from nose to tail. They
are used on the "front lines" in Thread fights. Greens mate
often, but are sterile (they never lay eggs)Greens are
always female dragons and are ridden by WOMEN and
OCCASIONALLY BY MEN.

Blues: Blue dragons are a bit larger than
greens, and are also fighters. They are about 100 feet, tip
to tail. They are right in line with greens, always male,
and are ridden ONLY BY MEN.

Browns: Brown Dragons are always male. They
are almost as big as bronzes, but not quite. They are not
quite big enough to be allowed in to a queen's mating
flight. Browns are ridden ONLY BY MEN.

Bronzes: Bronzes are always male. They're
not as big as the queens, but are the strongest and biggest
of the males and nearly always fly the queens. Bronzes are
ridden ONLY BY MEN.

Golds: Gold dragons are the queens, the
matriarchs, the dragon's only source for breeding. Golds are
huge, about the size of jet planes. Their hides are
shimmering gold, and they mate only with bronzes (sometimes
with browns, although they produce no gods and few bronzes)
Golds are always female and are ridden ONLY BY WOMEN.
