So, I wrote a beginning of a story (you can find it here), but I'm not sure of what should happen next. What should it take to bring Scootaloo back to life? A quest? Lots of paperwork? Something else?

I already scrapped most of the grimdark ideas - for a moment I thought about it as a possible Limbo crossover...

A quest would probably be a good idea. Keep up the good work!
