Era beginning/end
Only a story remains of the first Elves, supposedly gifted to the world by the Titans to protect their world after they died out. The First Elf Lord led the Elves into the central continent and began the first Elvish Tribe, the normal type of settlement of the era.
The First Elf Lord, who's name was lost to time, supposedly arrived on the continent after being created by the Titans. The tribe he led were the first to develop villages and farm the land. They had been blessed with the magic of the Dragons and the Wisdom of the titans, which led to the Elves being successful and spreading across the land over the next several hundred years.
