The Dragonsong War
refers to the thousand-year war fought between the Holy See of Ishgard
and the dragons of the Dravanian Horde
. The war began after King Thordan
and his Knights Twelve betrayed the pact between man and dragonkind by murdering the great wyrm Ratatoskr and stealing her eyes. Her brother, the great wyrm Nidhogg, slew Thordan and several of his knights in retaliation, but had his own eyes taken by Haldrath, son of Thordan. Though forced to retreat, Nidhogg later received a new eye from his brother Hraesvelgr and went on to harry Ishgard throughout its history and to the present day.
