Ectoplasm

Ectoplasm is the substance of which incorporeal undead (such as ghosts and banshees) are composed. Mux Manascrambler calls it "the very fabric of death" and "the spectral fabric of the dead", while Hornizz Brimbuzzle calls it "ghost energy".

Different climates lend different consistencies to ectoplasm, and it can therefore range from scorched, frozen, or airy to greasy, phosphorescent, and foul-smelling. Ectoplasm can animate into oozes called "ectoplasmic creatures". By tapping into the otherworldly energies contained in ectoplasm, it is possible to reach out to souls of the dead that have not yet left the mortal plane.

Ectoplasm exists in both the Great Dark and the Shadowlands. It also has some association with the Emerald Nightmare: the Nightmare-corrupted Wailing Caverns are inhabited by ectoplasmic creatures containing wailing essence (a substance believed by Mebok Mizzyrix to be the cause of the corrupted wildlife in the Barrens), and some fleshbeasts in the Nightmare drop ectoplasm.

In Desolace, Hornizz Brimbuzzle asked adventurers to help him gather "ghost-o-plasm" from Magram ghosts in the Valley of Bones in the hopes of selling the substance to the living Magram centaur.

Mux Manascrambler had adventurers use an ectoplasmic distiller to harvest different types of ectoplasm from undead across Azeroth in order to create an extra-dimensional ghost revealer that would allow them to speak with the dead. To provide energy that would keep the ectoplasm active, Mux used the core of a powerful lava elemental.

During the war against the Lich King, ectoplasmic residue from the ghosts of the Forgotten Shore was used as the reactive agent to activate the Forsaken Blight.

Custer Clubnik's bulldozer got clogged up with ectoplasm when he tried to drive it through the haunted woods near Lake Mennar in Azshara.
