The Terrapex Summit was hosted by the Magistery Guild in the year 100 CE, on the centennial of the Kraken's Awakening, and brought all of the world's cultures and peoples together to determine key strategic items leading to a more unified world.
After the threat of something as world-breaking as the Kraken, it became clear that we had a need for a means to bring the world together regardless of circumstances. While the urgency has somewhat faded for most of the world, the Elves remember the terror of continents bending and breaking on the ocean like seafoam on a windy day. The Magistery Guild determined a global capital for operations, Solace, solidifying their political influence, as well as a Common Language, and Common Era.
Numerous other territorial disputes were settled, and relationships forged that persist to this day, hundreds of years later.
