Star Wars Expansion: Sith Quest

In order to join the darkside, you must first travel to Tatooine. Then, you need to go to the jedi temple, and obtain a kyber crystal, as well as a holocron (you may have to just craft the holocron) in order to unlock your force abilities. Once you have a lightsaber and your force powers, train your abilities before heading to an ancient sith temple (aztec-like structure) and obtaining a sith holocron. Afterwards, use the sith holocron to unlock force imbalance, which will allow you to unlock the darkside once you've collected five sith archive tablets, which can be obtained from sith catacombs!

Looking to return to the lightside? Well, now you can! If you visit Endor, you can stumble upon an abandoned jedi training ground, which will house a jedi archive tablet somewhere within it!
