The complete history of Brio's life is unknown. She was born into the universe when it was young and she was one of many protectors of the cosmic consonance. It is documented that Brio was responsible for the welfare of fledgling life forms. However, presently she is presumed to be deceased. It is not clear if she participated in the great battle of the Gods. In this epic confrontation most of her Proemial God
brethren lost their lives to the World Devourer
, Galactus. Aegis
were thought to be the only surviving Proemial Gods. During their search of the demolished Kyln prison, Aegis and Tenebrous found the lifeless body of the Proemial God Antiphon the Overseer
. Thus leaving the unanswered question, is it possible that Brio is still alive and free somewhere in the cosmos?
