Rian Mikaelson [Sequel to "The Youngest Gilbert"]

(Had)Rian Mikaelson, son of Niklaus Mikaelson and Hayley Marshall, lost his mother when he was young. His Uncle Henrik and Kai mysteriously disappeared after removing Hollow from him. At least, her consciousness. Her powers, memories, mannerisms, and impressions remained. He has a close relationship with his older twin sister, Hope Mikaelson, who currently goes to Salvatore Boarding School for the Young & Gifted. The mysterious black pit opened on their school grounds, releasing monster after monster to hunt its residents. Rian discovered that he and his sister were the only things, that could close it. He didn't allow his sister to sacrifice herself, jumping heroically in the pit, erasing himself from everyone's memories. Hope, due to their twin bond, was the only one who remembered him. Sequel to The Youngest Gilbert. I don't own TVD universe or any other for that matter.
