Anaxim

Anaxims, also known as sheens, are a type of abomination from the roleplaying game Dungeons & Dragons, featuring primarily in the Forgotten Realms campaign setting. Sometimes mistaken for golems, these constructs are actually elementals native to the metallic ruins of the Glauer Barrens of Gontal. They were first brought into being by the primordial artificer Nehushta.

Overview
Anaxims have no definite physical form. Each anaxim has its own shape, made from a haphazard mash-up of various metallic parts. In most cases, the individual parts of an anaxim should not work together, yet still manage to function with murderous intent.

Anaxims are utterly mindless, even lacking basic animal instincts. While they possess a form of pseudo-consciousness, they are incapable of thought or reasoning, existing only to destroy any and all forms of life they encounter, even other anaxims. The average lifespan of an anaxim is only a month or so; driven to attack any creatures they meet, they often fall afoul of creatures stronger than themselves, or are slain by other anaxims larger and stronger than they.

Abilities

 * Immunities - As artificial entities, anaxims are immune to all manner of poisons as well as sleep or paralysis effects. They cannot be altered by any polymorphing spells and their mindless nature also makes them immune to any psychic abilities.
 * Darkvision - Anaxims can see up to 60 feet in complete darkness.
 * Rend - Anaxims use the numerous metallic blades adorning their bodies to slice through opponents.
 * Greater Dispel Magic - Anaxims are capable of temporarily cancelling out the effects of enemy spells and magical items.
 * Summoning - Anaxims can summon iron golems to aid them in combat.
