Alicorns are immortal. Earth ponies, unicorns, and pegasi are not.

Princess Twilight Sparkle has no intention of going through life without her dearest friends...

Even if she has to do something extremely questionable to make that happen.

After being summoned to a meeting with Wonderbolt Commander Spitfire, Rainbow Dash finally learns the truth about why she has been passed over by the Wonderbolts all this time. A little bit of Rainbowfire.

When your life is as dull a gray as the world that surrounds you, the mundanities can make it all seem meaningless. Sometimes all we need is a little color -- or six -- to reintroduce us to what truly makes life worth living.
