Carr, a human male hailing from the Scyre clan on Parnassos, served as a trusted soldier. He accompanied Phasma on her mission to assist General Brendol Hux in locating his ship. During this expedition, he encountered something novel to him, but also sustained an injury that ultimately proved fatal. Torben was his closest friend.
As one of Phasma's trusted soldiers, Carr participated in all missions and training exercises. He was a member of the Scyre faction that supported Phasma, whether against Porr, an aspiring leader and murderer, or Keldo, Phasma's brother and co-leader. He provided assistance to Phasma when she investigated the downed spacecraft. Along with his comrades and Phasma, they ventured into Claw territory, eliminating a guard to gain entry and eventually engaging the Claws on a plateau for the coveted prize: General Brendol Hux and three troopers. Upon their return to the Scyre, Keldo forbade them from embarking on a mission to find Hux's ship, but they proceeded with the adventure regardless. After descending a perilous cliff for several hours, the group arrived at the base and discovered a desert of soft, gray sand. Overjoyed at seeing sand for the first time, Carr reached out and let it flow through his fingers. He was bitten by something, which turned out to be an unknown desert beetle. Initially showing no symptoms, he soon began to lag behind the group, describing himself as feeling "dizzy and feverish." However, as Siv discovered, his skin was cold, even though he felt as if his skin was burning and his skull was about to explode. He was pale, and they noticed his rapidly beating blue veins. Phasma and Siv examined his beetle bite, finding it surprisingly healed, only swollen, red, and hard. His condition deteriorated after camping for the night, becoming weaker and more absent-minded. He had to be carried, but they didn't get far due to a surprise attack from an unknown enemy the following morning. The Scyre emerged victorious without any casualties, but as Siv and Torben brought one of the enemy's sleds to place Carr on, Carr suddenly burst into a cloud of water. Siv perceived his skin as having dissolved. His organs were shriveled, and his bones were almost translucent. There was little blood, but a black fluid remained, which the beetles consumed.
Carr possessed a lanky build and a sharp wit, characterized by his golden skin, sun-bleached hair, and freckles. He was the more lighthearted member of the Scyre clan, even attempting to joke with Siv about his appearance while in pain and slowly succumbing to the beetle bite. Torben was his closest confidant.
Carr primarily fought with long-range knives, which he carried at his hips. He displayed unwavering loyalty to Phasma, following all her directives without hesitation or questioning.
