The Kindly Balthazar is known for his charm and patience. He personally cares for all pups and regards pup-sitters other than himself as apprentices for life.
If asked about his past with the Queen, he quickly changes the subject. Despite his kindness he hates deep conversation and is more interested in distraction and charming the women of the pack.
Balthazar is closest with his son Frost, he's very supportive of Frost and makes an effort to be there for the prince.
