Drakanstorm

The Isle of Drakanstorm, also known as the Red Isle, is a large island in the Reaching Sea, one hundred miles to the east of the continent of Amara.

Raising of the Red Isle
Thousands of years before the Elder War, the deity Asgorath was pushed away from Amara by Elura due to his further experiments into creating more Dragons, creatures that he had created in the hundred years prior after his arrival on Aurus Elura. Asgorath was not banished from the continent, only asked to move away and cease his work. In his anger, he pettily chose to raise a new sub-continent and raised Drakanstorm from the seas off the east coast of the area that would eventually become Orukonus. On Drakanstorm, Asgorath created red Dragonborn and forced them to worship him, building a massive cathedral in the process.

War for Drakanstorm
Just thirty years after Drakanstorm was raised, Asgorath's descent into madness and cruelty had peaked, as he enslaved the newly-created red Dragonborn and began to form them as an army. Vel'oran, Elura, and the allied dragons of the young Coldreach moved to war against Asgorath, eventually defeating him and liberating the red Dragonborn. Most of the liberated moved back to Amara and settled in Coldreach, whilst some moved to Vel'oran, The Gnomelands, or stayed on Drakanstorm in various tribes.
