Star Wars: Tales of the Jedi Jumpchain

From the introduction: Welcome Jumper, to the Star Wars universe. However this may not be the Universe you know, instead you are placed several millennia before the loveable story starring Luke Skywalker, Han Solo, and Death Stars. Instead you find yourself in an era where the Republic that is in near constant conflict with the ancient Sith Empire, and Charismatic Dark Lords of the Sith start conflicts that last decades with aftershocks felt millenia afterwards. Depending on what time period you choose, you could be right in the middle of a war already, or just preparing for one.
