Demon

Demons are malevolent, evil spirits who reside in the ethereal world of The Mists. In the Underworld, Demons are responsible for the chaos that has caused the spirits of the dead to be mishandled in the realm of Grenth. Some few Demons enter the mortal world to haunt humans and other beings.

Demons in a broader sense
In Guild Wars dialogues the term "demon" is often used in a broader sense, for any evil creatures who fit the common myth image of a Demon or Daemon. Be aware that many of these creatures are not actually demons in the narrow sense (see next paragraph).

Also note that the "demonic servants of Abaddon" who take damage from Lightbringer's Gaze and trigger the effects of Lightbringer Signet are not necessarily demons in the narrow sense, and vice versa.

Demons in a narrow sense
Creatures classified as "real" Demons, in a narrow sense, belonging to the Demon species, are only those that take extra damage from a weapon of Demonslaying.

The use of the monster skill Demonic Agility or dropping of Demonic Remains indicates a demon.
