He's a certain Fallen that pops up erratically, according to legends. Other than that, would be nice if the Hive, Vex, and Cabal had their own little legends. [spoiler]First idea to do with Fallen, is Riksis, roaming about the Cosmodrome, and must be put down every week. Rewards vary from legendaries to exotics.[/spoiler] [spoiler]One I could make up would be a Precursor (brand new) Vex Minotaur with a Sol Divisive skin, and this certain Vex appears when you try to sneak into the Terminus, or anywhere outside the Vault. He should drop a random exotic weapon, due to his boss-like nature (about the size of Atheon, with a little boss encounter feel). He also should pop up more often on Earth, seen usually scanning stuff and then popping up elsewhere (in the 'search' state, the Precursor Minotaur of the Sol Divisive is neutral, and will even fight off Fallen and Hive).[/spoiler] [spoiler]Another one is a certain Knight/Wizard hybrid, a sort of 'Templar' that roams about and is clad in rather holy armor, and seems to've betrayed the Hive. This one you need to help him do a few random, simple, objective within the area. Usually concludes when the Templar Knight hails the Tower, simply saying "Objective complete. Next task please.", before he disappears (you are rewarded based on how many kills you got, rather than RNG).[/spoiler] [spoiler]There could be a certain Legionnaire who was raised by a Ghost, and serves as a Cabal 'Guardian', who travels to random areas. This Cabal is about 10% smaller than a usual Legionnaire, but has superior equipment, and can switch between 3 weapons (each of varying enemy factions). This one has 2 possible encounters; either you interrupted his work and must defeat him (when defeated, he goes back to Orbit, but drops a random legendary or exotic engram), or he needs you to do a few favours (when done, he delivers you an exotic engram of your choice).[/spoiler] Then there should be a dragon that [b][u]ever[/u]y[u]thin[/u]g [/b]is trying to kill.
