[quote]Hive and Fallen battle it out in the "Sky Watch" area, don't know how this happens though but seems pretty cool...[/quote] See devils lair "hive and fallen let's hope we don't stumble into the crossfire" also in the area behind skywatch where you find the ghost in the room with the "??" hallowed knight they are fighting, everytime you go in skywatch they are fighting, war between the Fallen an Hive is mentioned and is part of the lore for the game. So how did it happen you ask? It's part of the programming, Hive an fallen are basically battling it out for dominance on any given planet!
