Nalen Raloch was a Force-sensitive male Twi'lek who settled in the aftermath of the Great Galactic War, with its community on Tython. He was revered by the rest of the Pilgrims as a great hero. However, after submitting to the dark side, his mind was confused, and was under the influence of knowledge of the fallen Jedi, Rajivari. He would eventually try to destroy the Jedi on Tython, but his efforts failed when a Jedi Padawan was able to stop him.
