-Caladrius is the child of a lady-in-waiting at the court of silverkeep and a mecenary/adventurer who worked for a time as a bodyguard and companion to King Haric at the beginning of his reign.
-Despite being illegitimate, he was schooled with the other noble children, probably by order of the King and presumably as a favor to his father.
-The other members of court see him as a rake and are not quite sure why the King seems to indulge him so much, ie. let him stay around.
-One night while being attacked in an alleyway, he discovered that he had draconic powers when he breathed a blast of flame which immolated his attackers.
