Arlac Thene was a very stern but calm Twi'lek Jedi Master and then Templar of Twilight. He was also one of the founding members of the Templars of Twilight, The Founding Seven. He trained Tera Byssta to knighthood before they both left the Jedi with the rest of the founding members to seek out Dade Leviathan.
