Praedyth was a Hunter. Phanin Errata was there. He witnessed Kabr's fall after all. Osiris was either there or he just knew, because he sometimes investigates the vault or just sends someone else. Saint-14 was also there. (An old titan mark that is locked in the game called Saint can only be acquired through the Vault.) The more you know. [spoiler]who is Alymer?[/spoiler]
