Nilfheim is unusual for a black dragon. He is unnerving to be around, but not necessarily due to the natural fear of a big scaly predator that could eat you. His gaze lingers longer than it should, his mannerisms seem uncanny and out of place for a dragon, his voice seems hollow and distant. It almost seems like something in his soul, something in his very being, is missing or altered. It doesn't help his case that he has a fascination with trinkets taken from graves and tombs either. Physically, he's not much different from other dragons his age. He's just ... creepy.

Enjoys lurking in subterranean locations, particularly natural caves.

Potentially a little bit mentally impaired, due to some wyrmlinghood head injury which he can no longer remember.
