Canathdir is the son of Côleron of Calembel and Arasiell of Erynos. His mother used to be a farmer and his father was one of more well-off vault-keepers of Calembel. The two married in Calembel but Canathdir spent his early childhood in Lebennin as his mother took care of his grandfather there. When he passed away, Canathdir moved to Calembel at the age of seven.

His childhood there was good and the young vault-keeper in training was always fond of reading and writing. He could always found things good with his father even though he could be a demanding man at times. When Canathdir was twenty years old he was a fully learned scribe and bookkeeper and always kept a good relation with the farmers and crafters that came to the town's vault. His father died at the young age of 56 after which Canathdir took over the responsibility of the Vault rather quickly at the mere age of twenty-three. At this time the aspiring writer also started to write poems and short stories, often reciting them public for all too attend. Soon some of them were published and are still read at the bedside of children to this day.

Now he lives a quiet life, the quiet life that he has lived for years. The raiding of the corsairs have never troubled Calembel directly and the tales about the Death of the white mountain never affected him. He lives in a stately stone home in Calembel with his elderly mother. He is often jokingly called the "Gilded Mouse" by some of the less well of people in Calembel because of his sometimes cowardly behavior and work.
