Biography
Brother Constant and Poly Verisof were assigned to preach the word of the Church of the Galactic Spirit on the planet Siwenna in the Red Corridor. Constant was accompanied by her pet and steed, the bishop's claw Beki. One morning, Constant helps her fellow Church member, Poly, overcome a drunken state. She takes him to see a death threat towards the Foundation in the form of a crucified body near their camp on Siwenna. Knowing this as a sign of aggression towards the Foundation, they prepare for a later ambush on themselves.[1]
Later, Constant tries to drum up interest in a show but is cut short after locals try to apprehend her. After using her aura to protect herself, Poly flies down from their ship and the pair put on a show, resisting efforts from locals to remove them. They are called away mid-performance though as they are recalled to Terminus - the Vault has opened.[1]
Constant returns home with Poly and greets her Pater and her father, Director Sermak, where they discuss next steps for the Vault. She is present outside the Vault when it opens and Warden Jaegger Fount is killed, asking who "Hober Mallow" was as his name was etched into the surface of the Vault.[1]
