Byss

Byss was a godforsaken sorry excuse for a piece of crap planet there ever was.The only good things that happened on it was Annie totally Wookie-Nookied then killed that whinny cow Ahsoka,and GOD (aka Kyle Katarn) scored with Mara Jade Skywalker numerous times while Wormie Luke Skywalker traveled the galaxy in search of Sith Lords and a planet where inhabitents wouldn't kick the sorry shit out of his rectal orifice.Back on topic Byss sucked, although it did see MAJOR Wookie-Nookie's in it's time,before Darth Fred Fredburger destroyed it with a hammer thingy.

Origins
Byss was a collection of dust and rock particles banded together with lava and fused to create the godforsaken planet.The planet was about as useful as a freakin lemonade in a blizzard.

Little known fact.
In Count Dookies brief and failed attempt at a restaraunt franchise he opened McDooku's,as his master had copyrighted Dookies name in case he ever wanted to open a store or something.C'est la vie.
