Born to Straia during the early months of her rule in the Chamber. Born from a desire to strengthen the Chamber, not of love.

Erebor grew up in the Chamber, close to his parents but never affectionate. From a very early age his dedication to the Chamber was complete and total; he felt his grandfather Atrox's heart beating in the ground before he was even born. He spent his early years learning as much as he could from his mother and father both. He acquired quite a knack for diplomacy, and also learned how to strengthen and condition himself as a fighter. In May of 2015, Erebor visited every single kingdom in Beqanna as part of the Chamber's diplomacy initiative.

In late June of 2015, Erebor was promoted to Lord. Around this time, he was taken by the mysterious Grumblesnakes to a strange new realm as a birthday present for a spoiled, hateful girl by the name of Nerissa. Erebor survived against some pretty impossible odds, and emerged from the ordeal on June 8th with a new power, heat manipulation. Erebor was dark wine-red with navy blue and forest green streaks in his mane and tail for some time, but eventually faded back to his normal black - although some green and blue streaking is still evident in his mane and tail, it is not nearly as prominent. Around his upper left front leg he now has a tribal-styled tattoo, featuring stylized images of a teddy bear, a pegasus, a female cowboy samurai, and a humanoid rabbit interlinked by tribal-esque markings.
