Name: Callen
Age: ???
Species: Fae, more specifically a Dullahan
Personality: Callen can't really be described as having much of a personality due to lacking a head to convey emotions through expressions or vocal communications... luckily, actions speak louder than words, as he is a rather persistent hunter if someone ends up becoming his mark. Neither heaven nor hell will stop him from chasing down his target until he claims their life, aside from that. He does act like most Dullahans, being a naturally isolated individual besides having his horse, of course. He does have a fondness to it, which does make him angry if someone attacks his horse. Even if the horse can't die, he takes it as a grave offense to him. Rather than someone hopeless, attacking him to stay alive.. as for how he is with prey, depending on who they are as a person. He will take immense satisfaction with ending them or even prolonging their suffering, but if they are a better person. He would make it quick and easy, but even then. If they show resistance, it just causes him to feel thrilled with the hunt even more. To which now, his prey has to deal with the fact that they enthralled him. By making themselves enticing prey and there is no escape from such a fate now.. outside of hunting, he despises being noticed by others. The only exception would be if he were to have a mate. Even then, meeting a Dullahan isn't a thing one would wish to do

Weight: 152, but can be changed due to his abilities

Weapons: Callen wields an axe as his weapon, as for secondary weapon. He carries a 1851 Colt Navy Revolver. As for the third, he has a whip made of human spine
Weaknesses: Gold. Mainly, the fact it scares them. Meaning, it doesn't actually hurt them at all, running water. But can be bypassed with help, his own head. Taking his head will make him obey the one that holds it or, if destroyed, will sever his link to the mortal world. He is also weak to the sun, although it really isn't a weakness more or less a condition that he can only hunt at night

Background: The story behind this Dullahan is one that: not even itself knows. The only thing it knows for sure is its name. Which was in his coat, printed on the back where the fabric would've touched the back of his neck.. although now knowing his name is Callen, no memories even emerged from such a revelation. Not even the weapons he carries tell him anything, even the gun he possesses. As he doesn't know whether or not it belongs to him from his past, but even then. He wasn't discouraged from trying to uncover his own history, no matter how long it takes.. but on his journey to uncover who he was, he had to face the trials of being a Dullahan. As his nature to hunt and kill people isn't something he can resist, to which with time he learned to let go. To stop resisting against his new nature, as it agonizing for humans to refuse to eat, drink, or even breathe.. and with doing so, he has never felt such relief and satisfaction with doing so. Embracing what he is now, even though deep he still feels that the Callen that was once human. Wouldn't take lives so easily and take satisfaction from such an act, but to him now... The Callen that he was once before, the one that was human. He is now dead, and he is all the remains. He is the only one who can try to piece together the human Callen's past
