Alak was an ancient monarch who ruled the Rakata Infinite Empire, being the second ruler of that civilization, according to the Rakatan King List. According to the list his reign lasted 1,500 years, but historians debated whether or not he really existed or was mythological.
His race was unknown, because the King List never stated it one way or the other but vaguely implied that he may have been a Kwa rather than an actual Rakata, a reptilian race from Dathomir that discovered Lehon and granted the primitive natives space travel technology.
