Ah, Shoryu, my friend, I'm glad you have other ideas. The mutant alicorn simply won't work, for reasons that will become apparent in-game, if we ever get that far. Let's just say there's a reason Twilight's experiments have been unsuccessful. And, to everyone, sorry. No alicorns, of any type.
PM me as many of those other, strange, unique ideas as you feel comfortable with, and we'll discuss, yeah? I'd like to see what you'll come up with.
