The Draconic War

The Draconic War was a major war between Nocturn and Vala and a major part of each country's history and culture. While dragon-hunting has been a tradition in both of these cultures for centuries if not millennia, this war is why its ramped up to the point of dragons being near-extinct.

Overview
Nocturn and Vala used to be in a state of near-constant war. The only thing keeping them from massacring each other was the massive mountains in the middle of their continent and vast ocean in between the two. But in this particular war, Vala had almost defeated the Nocturnians. Where Nocturnians specialized in diplomacy and magic, Valians specialized in valor, war, and sheer willpower. They had managed to cross the mountains, and with little defenses, Nocturn was almost completely conquered.

All would have been lost for them if it weren't for a Wizard: Emilie Regene. Using her arcane knowledge, she opened a portal to the astral plane and employed a group of Metallic dragons to help. With their help, they won the war, but it was at a great cost. With them vulnerable, a silver dragon named Xyrvinth held a coup de tat and took over Nocturn for 50 years until the high elves, with the help of their former enemy Vala overthrew the dragon and put in a new monarchy. Xyrvinth escaped but was found dead outside the palace weeks later. It is unknown who killed Xyrvinth for sure, but most people assumed it was the son of the overthrown king or the royal knight who helped restore the current monarchy.

They hunted down the rest of the metallic dragons until they were thought to be extinct.

The king who took control was the father of the current Queen of Nocturn, Queen Anabelle of Vinfort. His name was Victor de Vinfort.

Modern Impact
This war had much more effects than the average war on Nocturn and Vala. The metallic dragons caused a renaissance in the study of history in nocturn and dragon-slaying in Vala. Among Humans especially, the story of Xyrvinth echoed previous legends of how the humans and elves overthrew the dragons before. (see here)

Hunting metallic dragons became a massive prize, neither country wanted to let a single one get away. Dragonslaying became especially popular among Humans and half-elves, as it was a fast way to get the glory. The famous general Hugo Ligüerre is said to have killed the last one, a brass dragon about 20 years ago.
