Darth Twil'a was a Sith Twi'lek. She kidnapped Darth Dractomius when he was an infant to be a future Sith Lord and future lover. She knew that they would have too big of an age distance when he was an adult, so she used an age steroid to slow down her aging until their ages were the same. In the year 395 ABY, the two had a child who later became known as Darth Purge.
