The day had finally come. The immortals of Equestria, Celestia, Luna, Chrysalis, and Discord, had finally graduated from high school. And where do they go? Why, the most prestigious college of magic in the entire multiverse: Ravnica Polytechnical! One problem arises, however; roommates are assigned by major.

This takes place in the Ravnica plane from Magic: the Gathering, but that is mostly irrelevant for now. Rated Teen to be safe.
Image is "Leave Her Alone" by sophiecabra. It was the best thing I found with all four of the Immortals in one picture. I will change it if I can find one that just has Cthulhu and Discord in it.

NOTICE (9/26/2013): I am opening up Discord and Cthulhu: College Roommates to guest chapters and prompts. Each chapter should show the characters dealing with university life. PM me if you're interested.
