Twilight Sparkle is now an alicorn and possibly immortal.
Would you stand watching your loved ones die?
Are you willing to pay the price of immortality?
There's always a choice.

Well, I don't know if Twilight is immortal now, but the thing of alicorns living more than ponies, pegasus and unicorns seems to be canon. This is my first fanfic, so I'll receive any constructive critique gladly.
