Yes almost all relics have and associated knightley oreder that have been traind to fight and to wirld magic in a way that mimics the relic power.
For example the Knights of the Blue Hand
are connected to the Hand of Azazel

and can simulate the all-consuming and partially sentient black fire the relic prioduces.
I'm figuring out the others (heres the list https://miro.medium.com/v2/resize:fit:720/format:webp/1*SAKAKep0NNh-DYTh0urs6A.jpeg)
But for example the knight of the tounge of Mephistofelese will have some way to compel people to not break oath and contracs, the one of the wing of belzebub will create wind that can heal or make ill
at osme point i will have to make a portrait for all of them!
