Aberration

Aberrations were a category of creatures consisting of alien or otherwise biologically aberrant beings. Aberrations did not originate in Exandria and some originated or were otherwise associated with the Far Realm.

In Tal'Dorei
In Tal'Dorei, aberrations were perceived as the vilest and most intelligent creatures of the monstrous races. Anyone who attempted diplomacy with any aberration tended to become food or their thrall, leading to them also being considered irredeemably evil. Aberrations, in turn, considered Exandria's creatures to be nothing more than food or potential property.

Aberration civilizations existed in the Underdark beneath Tal'Dorei, including the mind flayer colony in Yug'Voril, beneath Kraghammer, and the aboleth brood in Salar, below Emon. Long exposure to the aberrations' psychic energies created veins of azuremite, which can be mined and refined into suude, a drug that affects spellcasting.

A magic item called the Aberration Bane Longsword was in possession of Vox Machina member Scanlan Shorthalt.

In Wildemount
The Mighty Nein, an adventuring party based in Wildemount, once found a Scroll of Protection set to protect against aberrations. Caleb used the scroll to great effect against Lucien and the Somnovem.
