I like explaining the plot to Ascension because no one seems to realize that there is one. Come on guys, this stuff is important! Way back in Return of the Fallen we climatically got to face the first god that needed to be slain, Samael. Well turns out he had a son who was being held in a crystal prison in the Void. When Samael died his son got kind of mad about it and shattered his prison. Now wouldn't you know it, those shards starting showing up all over Vigil. I guess people began to figure out that something wasn't right when the dark energy shards started appearing. That's about when Erabus, son of Samael showed up to unleash some darkness. Or he is the darkness and he's being unleashed? Either way, it's time to slay another god!
