Formis

The Formis seem to be a race of sentient constructs. They are capable of speech, but do not require food, water, or sleep. Their bodies are made from metal, which can still rust. They can be healed using divine magic, and also consume potions.
==== Mark I Formis ====
Called "Formis Titans", they were large, powerful, but less intelligent than the designs that followed.
==== Mark II Formis ====
The most common type of Formis. Durable, strong, yet at the same time not overly bulky like their predecessor. 
Examples include Factus Formis, Pontus Portalis, Apollo, and Dolos.
==== Mark III Formis ====
More slender than the Mark II, the Mark III possessed a more natural affinity for the magical arts, though how this was accomplished is not known.
Examples include Erebus.
==== Mark IV Formis ====
Called "Formis Colossus", the Mark IV were massive constructs wrought from a variety of materials. They had unrivaled power and enough agility to grab Dragons from the sky, tearing them asunder.
Examples include Kronos.
==== Mark V Formis ====
An advanced model, they resembled other mortal races to an unprecedented degree, but had glowing orange eyes and a rune on their forehead.
Examples include Daedalus, and Nathaniel Lightheart.
==== Mark 6 Formis ====
The most recent frontline combatant-type Formis. Also known as Formis Sentinel, they are taller than Mark Ones and Mark Twos, but are lean and agile. They are ultimate warriors, boasting high stats across the board.
