|Oldest brother to Queen Maeve of Beldain|
|Family|| Maeve Corrigan|
unnamed mother: former Queen of Beldain
Augustine is Queen Maeve's oldest brother and is her loyal protector. He is skilled with the sword and often helps Maeve train. He also goes on missions with Maeve and is a trusted member of her council. He helps defend Maeve in battles and against their brother, Tristan, when he is overpowered by the energy of death and attacks Maeve.
Following the Beldish law that girls inherit the throne, Maeve appoints his newborn daughter (her oldest niece) Crown Princess of Beldain after her. This gives Maeve the freedom to marry Lucent.
