Angels

Angels are robotic-servants created by Humanity, designed to maintain and defend the various Habitats placed around Terra. Various Angel varients exist, with each being assigned to a specific task. The Angels are revered by followers of Precursorism as "holy attendants of the Precursors ", and are treated as holy relics to their religion. However outside of Precursorism, Angels are seen in a generally negative light due to their aggressive nature towards those that do not worship Humanity.

The exact number of Angels roaming Terra isn't known, as the codices of Habitats do not catalouge them. Desecrated wrecks of Angels are commonly found, implying that they once roamed the planet in greater numbers.

Seraph
Seraphs are the highest ranked of the Angels. They were created by Humanity to directly oversee the opening of the Habitats and their subsequent awakening. Because of their duty, Seraphs posess the highest intelligence of the Angels. Very few Seraphs were built, and present-day only two are known to still be active: Hosanna, currently in service of Abdiel, and Samson, whos whereabouts are unknown.

Cherub
While the Seraph's were made to oversee the openeings of the Habitats, the Cherub were made to protect them. As they were designed purely to kill, what a Cherub has in firepower it lacks in intelligence. One Cherub, Aliakim, attacked Leo in the Awakening Era and was ultimatly destroyed by the Cat-folk while protecting Habitat 000.

Thrones
Thrones were made as knowledge keepers for each Habitat, knowing its inner workings, the history of its region, what species it carries, and many more subjects. Thrones were what informed the folk of Terra about Humanity, and were instrumental in the adaptation of their technology as well as their rapid intellectual evolution. As they were designed to self-destruct a set amount of time after their Habitats activation, all Thrones have likely been destroyed.

Virtues
Some decades prior to the Habitats opening, Virtues were released en masse to prepare Terra for Human resettlement. Long since shut down, the wrecks of Virtues are a common sight across the planet.

Archangels
Archangels are the primary combat robot built by Humanity. Released alongside the Virtues, Archangels were built to protect Humanity from the wild once they were released. Present-day, a large number of Archangels roam the areas around Habitats, attacking all on site.
