Ciaphus Cain (HERO OF THE IMPERIUM!) is a Looper in the Warhammer 40K Loops and a member of the Imperial Guard Commissar in the Imperium of Man.
- Element of Loyalty: Ciaphas Cain is the only non-native Looper to permanently acquire access to the Element of Loyalty, earned during an attack on Equestria by Nightmare Moon and the Smooze.
- Leman Russ: The two have a good relationship, enough that Ciaphus was able to become part of Leman's circle of Element-Bearers.
- Pinkie Pie: Ciaphus became deathly afraid of Pinkie after he Awoke in a Loop where she had replaced Slaanesh and took over the universe with chaos and parties. The two have since made up after she apologized for upsetting him.
