What undead creature haunts Norse burial mounds?

What undead creature haunts Norse burial mounds? The draugr is the undead creature associated with Norse burial mounds.

In medieval Icelandic sagas, a draugr is a malevolent revenant: an animated corpse that remains physically present rather than becoming an intangible ghost. Draugar commonly dwell in graves or burial mounds and guard treasure, weapons, or possessions buried with them.

One related term is haugbúi, meaning “mound-dweller.” A haugbúi generally stays inside its grave and attacks intruders who trespass, while saga draugar can display broader supernatural powers and may leave their burial places. Stories describe them as unnaturally strong, swollen or darkened, foul-smelling, and capable of spreading fear or illness.

Modern films and video games often portray draugar as uniform mummified zombies, but older folklore is more varied. The term also appears in sea and ghost traditions across Scandinavia. “Wight” is a reasonable translation in some contexts, but draugr is the specific Norse name asked for here.
