The Dragon's Empire: ENDeR_experiment
The empire was at one point too greedy for power, so they manipulated their knights into abominations from the "Gazer Project", which ended horribly.

Extra detail of the The Gazer Project (If you like reading)
These abominations were made under Forced mutation and prohibited magic rumoured to come from The Deeper Void (or simply, Endermen Underworld). These can't speak, but can still scream with no mouth. Their scream are the voices of The Deeper Void, as it is rumoured. They leave blood tracks everywhere as they go. But they are made to fight, so The Empire told these un-ender creatures to fight enemies under their control, as they told them telepathically. Beware these beasts, they may "Gaze" at you, to that as Endermen's nature is to kill the humans to that of when if they stare at you. If that happens to a Gazer, not only they'll fight, but blast a beam out of their face, disintegrating every piece of you. These beams are very powerful, but it is created in The End, so they have one, faulty weakness: Stone. Their beam is an unknown form of matter, also being only electricity. But their beam is still unindetified because it's actually a different form of electricity made out of unknown matter. Thus, stone, not being a Condenser of electricity, can sustain all of it without a single crack and not leaving any shocks upon touching it.
