After Rainbow Dash succumbs to a terrible accident, Twilight Sparkle and her remaining friends gather for the funeral. But who is the strangely-familiar Pegasus pony standing in the doorway? Who are the two Ponies in Black who accompany her? And how does this relate to Cloudsdale's mysterious Rainbow Factory?

Twilight finds the answers are stranger - and more literal - than she could possibly have imagined!

An... alternative... take on Woodentoaster's unbelievably awesome Rainbow Factory.
