Ask AI: In Fire Emblem: The Blazing Blade, what would have happened if Nergal had been successful at the Dragon's Gate?

If Nergal had been successful at the Dragon's Gate, he would have summoned a massive number of immensely powerful dragons to the world. Using his ability to control the dragons, he planned to throw the continent of Elibe into chaos and feed off the quintessence—or soul energy—of the casualties to increase his own power drastically. The events of Fire Emblem: The Blazing Blade make it clear that if this had occurred, it would have likely ended in a massive catastrophe, with a great loss of life and potentially the end of the human's rule over the continent. Thankfully, this outcome was prevented by the protagonists' intervention. It's also likely that if Nergal had been successful, the story in the sequels of Fire Emblem series might have been drastically different or perhaps not existing at all.
