This story is a sequel to Trial by Kinship
Every year, Princess Celestia hosts a special Inter-Species Conference to recognize the creatures who aren't strictly equine. And with the political climate of many nations seeing a massive paradigm shift, this year will be most important. Not only will new alliances with Yakyakistan and the Neko Shogunate be recognized, but the reemergence of Griffonstone has given rise to a new ambassador from the Griffon Kingdom in the form of the town's savior, Gilda. But no one is more nervous than the newly-appointed Dragon Lord, Ember. After all, never in the entire history of Equestria has a dragon ever attended the Inter-Species Conference. She has to make the best impression possible, even though diplomacy is not a dragon thing.
However, that turns out to be rather difficult when a dark dragon wielding mysterious magic crashes the party and outright defies Ember's rule. But how could this be? The Bloodstone Scepter should grant a dragon absolute authority over all dragonkind. The only dragons who are able to resist its power are the elusive Dragon Magi clan, and they aren't violent at all. Well, one is, but she's still learning the ropes. Luckily, she's attending the conference as well, and she's got Ember's back.
Not allowing this insult to stand, Ember vows to get to the bottom of this mystery along with a group of noble vigilantes from the Mild West. Meanwhile, Celestia, Gilda, and Little Strongheart band together to protect the posse from a pair of dragon poachers who haven't quite learned their lesson. This will either be the dawn of a new era for dragons, or the shortest reign of a Dragon Lord ever recorded. Hopefully, the hidden secrets of the Dragon Magi will prevent the latter.
