Caelum'sae is the youngest of 7 children, with 3 older brothers including his twin brother Caelen'to. His clan lives on an isolated isle and is heavily involved in the archiving and amassing of unique relics and tomes for the Sharlyans. As his clan prioritizes and prefers females, male children beyond the first born are generally exiled into the world to gather the resources and relics that the clan is trying to preserve. Recently reunited with two of his other exiled brothers - including his older twin - Caelum has distanced himself from his clan's wishes and instead has started to build his own library and collection of books!
