User:SilverTiger12/List of aberrations

A list of all creatures classified as aberrations in D&D.

Aberration - creatures that were wholly unnatural; that did not fit into and typically were highly disruptive to the natural order.

Aberrations did not have a single source, but could arise from one of several different sources:
 * From an alien plane (mainly the Far Realm, though some were thought to originate in the Ethereal plane)
 * Far Realm (native) - self explanatory, many aberrations were direct natives of the Far Realm
 * Far Realm (warped) - creatures of the Material plane that visited the Far Realm were often warped by the magic of that place into aberrations (i.e. kaorti)
 * Far Realm (made) - aberrations hailing from the Far Realm often created new aberrations wherever they settled.
 * From an otherwhen world.
 * Mage-made: created by a powerful and only questionably moral spellcaster of some kind.
 * Deity-made: Created or transformed by a deity
 * (Specific to Eberron) Originating in Xoriat or created by the daelkyr.

Additionally, aberrations could be differentiated from magical beasts, monstrosities, and monstrous humanoids in that they were antithetical to the natural order:
 * There is no ecology they are native to except, possibly, in the Non-Reality of the Far Realm.
 * They have no predators, except possibly other aberrations, and even if they die no predators, nor carrion-eaters, nor even fungi, will feed upon their corpse.
 * They have unusual and inexplicable diets, either very broad (to the point of digesting things that they should not be able to), or weirdly specialized (i.e. illithids eat brains of sentient people and nothing else). Particularly, those with specialized diets may feed on substances or energies that occur only rarely or not at all in nature.
 * Unusual reproductive habits or requirements.
 * Aberrations typically have a severely deleterious effect on their local environment, by way of their above traits.

Additions
Some creatures have not been classified as aberrations in canon, but their origins and nature match those of aberrations.
 * Uvuudaum (from Far Realm (native))
 * Kaorti (from Far Realm (warped))
 * Thessalmonsters (Mage-made)
