Veyl Suilven (Older Brother of Cairn Suilven): Veyl is consistently supportive and protective of Cairn. His first action after being un-possessed was to back him up in a fight. He was the one who pulled him up when he fell into a deadly mist, dropping the guy they were supposed to interrogate to do so with no hesitation. When their group learned that they'd been lied to about the nature of the job and their world, Cairn started mentally spiralling, and Veyl was there to comfort him, reassure him that it's okay to not have the answers, and even share his deepest secret just to let him know he wasn't alone in his anger/fear (it turned out Cairn already knew the secret but it's the thought that counts). When Cairn offered him the chance to help with his detective mission, Veyl agreed with no hesitation. And when the two of them ran into a hellbeast intent on killing Cairn, Veyl literally sacrifices a piece of himself so that he can be strong enough to fight the beast and save him.
Tuffnut Thorston (Twin Brother of Ruffnut Thorston): Tuffnut and Ruffnut have a strong love/hate sibling relationship. They share an inseperable bond and rarely spend much time apart even if they do enjoy quarrelling with one another. On occasion Tuffnut is willing to help his sister. Tuffnut was worried for her so asked to leave Scauldy behind and was pleased when she was safe despite the sacrifices she made for Scauldy. When she has to say goodbye to Scauldy and is sad Tuffnut teases her making her smile again. When Tuffnut is kidnapped Ruffnut's main focus is to get her back even fighting Ryker to do so. As twins Tuffnut and Ruffnut have an invisible connection to aone another. They can understand each other's thoughts and ideas without speaking. Several times they finish each other's sentences or have the same idea at the same time. Wherever one goes the other is never far behind. Tuffnut and Ruffnut can work extremely well together and can synchronise their actions so they act at the same time.
