Inevitable

Inevitables were lawful intelligent constructs native to the Clockwork Nirvana of Mechanus and the plane of Dweomerheart.

Description
Inevitables varied in form according to their purpose, yet one feature they had in common was a clockwork nature, with gears and pistons in place of muscles. Their bodies and armor were gold and silver and their eyes shone with a golden light.

Personality
In contrast to the majority of constructs, inevitables were intelligent beings capable of thought, memory, and learning. But not a lot—their sole purpose was to enforce whatever fundamental law of nature for which they were programmed and they had a one-track mind in its pursuit and oblivious to other matters. Despite this, individual inevitables could have or develop certain idiosyncrasies in their programming, producing slight variations in their behavior and responses. For this reason, they were regularly recalled for reprogramming.

History
The inevitables were created by Mystra, as she was guardian of the laws of magic and they were tasked with enforcing the fundamental laws of the universe.

However, others reported that Primus, the One and the Prime, ruler of Mechanus and the modrons was responsible for creating inevitables with the purpose of establishing order in the dealings between inhabitants of the planes.

Locations
In the Great Wheel cosmology, inevitables could normally be found on their home plane of the Clockwork Nirvana of Mechanus, as well as the similarly lawful planes of the Nine Hells and Mount Celestia. However, they could appear anywhere when in pursuit of their quarry.

In the World Tree cosmology, the inevitables were found in Dweomerheart, the realm of Mystra.

Activities
They sought out and punished those who broke fundamental laws, such as "Bargains should be kept", "The guilty should be punished", or "Everyone dies eventually". Each type of inevitable would target specific infringements, but all would act without emotion, punishing those found guilty to the letter of the law.

Combat
In battle, an inevitable focused entirely on its target and completely ignoring others. They were programmed to avoid innocent beings, but not their accomplices and agents, which could occasionally cause conflicts in their programming. It might attack a creature that got in its way, but would delay no longer than necessary before it engage with the target again. Despite this, it did not neglect self-defense at all: if an inevitable was attacked with what it viewed as deadly force, it would respond in kind, and an inevitable would act to preserve its existence.

Abilities
While inevitables varied in their design and powers, all could regenerate to repair damage sustained, provided they were still functional. However, chaotic weapons and the natural attacks of beings of chaos overcame their natural resilience and could not be regenerated.

Similar, as beings of law, inevitables' weapons and natural attacks overcame the natural resilience of beings of chaos.
