The ancient dragonborn dynasties apparently had no interest in exploring and conquering other planes of existence. Consequently, when the beautiful elven kingdom of Cendriane was threatened with annihilation by dragonborn armies, its leaders evoked powerful rituals in a desperate attempt to shift the entire kingdom into a twilight reflection of Io'Tamrin called the Feywild. Although the elven mastery of arcane magic was unrivaled, their rituals failed. Cendriane’s transposition into the Feywild shook the kingdom to its foundations. All of the magic in the world couldn’t keep its towers and walls from crumbling into ruin, and few elves survived the calamity. The survivors remained in the Feywild and began the long process of rebuilding Cendriane’s capital of Amethystra. These elves cloaked the crystalline city using the magic of the Feywild, hoping that intruders from Io'Tamrin would have a difficult time locating it.
Roughly two centuries ago, elven spies returned to Io'Tamrin to observe the changes there. They were shocked to discover that most of its lands had sunk beneath the sea and that the dragonborn dynasties of old were no longer a threat. A few families of elves have since rejoined their kin who they left behind, but they guard well the secrets of their new homeland for fear that knowledge of the Feywild’s abundant land might spur others to invade it.
