Background: Yelsain was the homeworld of
many Jedi. It was a forest planet, and was home
to massive trees, some as tall as 400 meters. The
atmosphere was high in oxygen, so offworlders
tended to become dizzy at first, particularly
when they exerted themselves. However, they
did not get as winded as they normally would.
The high oxygen content also helped create the
spectacular weather for which Yelsain was
famous, with immense thunderstorms
practically a nightly affair. The animals which
inhabited Yelsain were large, averaging twice the
size of a Human, and the carnivores were
dangerous. The two most dangerous creatures
were the trogliths and the garaths.
Under the Empire, the population suffered
systematic denial of basic rights.
