Celestia's plan to reform Discord had worked. But as he and his new pony bride began to settle into a quiet, peaceful life, a letter from a family member arrives.

Discord is now forced to 'pony up' to his new friends, and share with them his origins, before his past finally catches up with him.

A city where there is no day. A city where technology is years ahead of the outside world. A city where all races are welcome. Especially those that thrive at night...

Zecora foal sits the cutie mark crusaders, and tells them the tale of how Twilight made every pony go bald.
