Marumor

He has no clue he’s dead, which is quite a feat of denial, all things considered. Either no one’s noticed, or they were smart enough not to tell him. In all fairness, he is rather skilled at hiding his “condition” and he’s not particularly social.

Though, it's not quite a case of denial; rather, it's never even crossed his mind.

The only thing left of his body is what remains of his skeleton. A handful of bones have been replaced; an ironwood rib, the bones of a high elf's pinky finger, and so on. It's always hard to find a good fit, and he's currently missing his right arm. His own bones were stolen by a hound and he has yet to replace them.

Few will ever see him like that. He isn't presentable unless he's fashioned flesh from some combination of magic and material components. It makes up a fairly accurate representation of what he looked like before his "condition" and it's usually quite passable for the interactions he needs it for. However, many major organs are useless to him. He has no blood, nor a heart, nor pulse. His temperature is low, but he is still fairly warm at his core. His extremities tend to be much cooler. "Breathing" isn't always something he does.

His senses are also mostly dulled. He's nearsighted and can't make out faces well past ~25 feet. His sense of smell is weak, but his sense of taste is a bit better. His hearing works well enough for his needs. He's invested most of his resources into touch; otherwise, he can't function well and tends to feel a strong disconnect from his body.

In addition, he can't hold much weight in his right arm as it currently is. Hand him too much and he'll just drop it. 

Little lamb, won’t you take the hand of this faithful servant? A honeyed tongue coats his bitter-almond intent, but salvation lies in store for both of you, assuredly.

When more tender morsels won’t be snared, he’ll bait the hungry sinners next. Let the wolves chase this rabbit back to its den, where the maw of greater beasts lie in wait. Predator becomes prey, and their would-be victim feeds on the carrion.
