Well, I'm planning to have you meet Asra Nox after going through a gateway the Occasus Cult constructed that leads into a giant vault in another dimension. In the giant chamber she waits for you near giant machine constructed with ancient technology she gathered from other vaults (including one that you go through for the mod's first mission). The machine is designed to draw in the power The Ruin and The True Ruin released when they died. After a long cutscene (which can be skipped) where she talks about why she's doing all of this she activates the machine and absorbs the combined power of The Ruin and The True Ruin. When the dust clears you're on a platform floating in a clear sky facing the powerful god-like being that Asra Nox has turned into. She'll look basically like her self, but surging with power and probably with large wings and a large blazing sword. I'm not going to tell you much else because spoilers, but I plane to make it so that you can't use admin mode in the mod's missions.
