The War of Many Names was the second realm-wide, centuries long war against Tiamat the Dragon Queen, and the countless Dragon's she had been raising for nearly a millenia on the island of Kiston. The War lasted so long, and evolved on so many fronts, that it is still highly debated whether it should be treated as one very big war, or broken up for the distinct wars that rose and fell over the centuries.
