Hey all Morty here again. I've been playing SWTOR recently and doing a little background searching on some of the characters in the game and none have been more interesting than the story of Darth Malgus and his Twi'Lek lover Eleena Daru. The story is actually quite basic:
Darth Malgus, his true name being Veradun, was trained by a Pureblood Sith Master, Vindican. During a trip to the Outer Rim world of Geonosis, Veradun discovered the young Twi'lek slave girl, Eleena Daru. Upon seeing that Daru was abused and physically beaten by her owner, Veradun killed her master and took the Twi'lek as his own. Although she remained his slave, the two became lovers and he eventually came to treat her as a wife, despite the Empire's anti-alien policies.
So the story is kind of basic, Malgus saves Eleena from her abusive life and gives her the opportunity to better herself. While on the outside they may seem like a standard master and slave (Malgus giving orders and Eleena obeying to the letter) but as they continue to be togehter their relationship grows to a deeper level to where Malgus treats her like his wife rather than a slave, but they decide to keep that hidden due to what it could mean for Malgus' career as a Sith and the Empires anti-alien policies.
So if you're interested in this pairing please PM me.
