Ambrosin Calore is King Triarch of the North in the Kingdom of Tiraxes.
After his mother, Queen Andura Calore, died, he left Norta to seek fortune in the west. He was unable to succeed to the throne because his grandfather, King Aerion Calore, had decreed that the line of succession would depend on ability and not gender. Unlike most members of House Calore, Ambrosin was not a burner. Silver abilities pass from the father, not the mother. So Ambrosin was a blood healer like his father, Brannon Blonos.
Regardless, Ambrosin is highly skilled and nearly immortal because of his ability. He continues to live as King Triarch of the North. He has not married, but instead has had various companions. His children and descendants are Tiraxian royalty.
Ambrosin is a very gifted Blood Healer, meaning he has the ability to heal himself from almost all wounds and disease and achieve considerable longevity.
