Precursors (Necros)

The Precursors are the most advanced species to have ever lived. They preceded the Forerunners, and their technology far exceeded the Forerunners as well, eventually allowing them to leave the galaxy.

Early History
Precursors existed for at least 100,000 years before the Precursor-Hydra War. Their history had many, many ups and downs, filled with peace and war, as are all histories.

The Precursor-Hydra War
The Precursor's encounter with the Hydra would be their last stand. The war with the advanced parasite would kill off most of the Precursors, while the Hydra would suffer little. After the war, the Precursors soon left the Milky Way Galaxy.

The Aftermath
After the war with the Hydra, the Precursors were devastated: most of what they had created had been destroyed, their planets had been ravaged, and most of the Precursor population was dead. However, a worse fate was yet to come.

Technology
The Precursors were, and still are, the most advanced species to have ever existed in this galaxy and likely all others. And their technological achievements matched this fact.

Weapons
The Precursors used a variety of weaponry, varying across greatly different fields, such as heat weapons, freezing weapons, kinetic weapons, and various other kinds.

Robotics
The Quad Mech was the most basic of all Precursors mechs. It consists of a large head with a single, red optical lens on four legs, each ending in a spike. It was produced en masse to combat foes, beginning with the Precursor Civil War. Its' design was simple and effective enough that it survived with minimal changes down till the fall of the Precursors.

The Smasher has two giant arms ending in two large shock-wave emitting orbs, as well as a large cannon on its' back.

The Heavy Crusher is a giant version of the Quad Mech, created to lay siege to Intga cities, fortresses, and bases.

Starship Technology
The starships that the Precursors created ranged from very small to very large in size.

Genetics
The understanding and capabilities of cloning that the Precursors had was quite large. By the time of their downfall, they were able to clone anything within a very short amount of time, varying due to size. But, one thing that the Precursor could not do was graft new limbs to their bodies, as their DNA would not allow them. Though they could clone a limb in under an hour, their bodies would reject any limbs that were grafted onto them, not accepting them and causing them to die. Thus, the Precursors instead created cybernetic limbs and such. The Precursors were also extremely skilled in mechanics, and this included cybernetics. Their cybernetics ranged from cybernetic implants, far more precise and useful than both Human and Covenant could ever dream of. If, and when, necessary, the Precursors also created artificial, though uncannily life-like, limbs.

AI
Precursor AI were very intelligent and lived for very long times. Though they could accumulate vast amounts of knowledge and live for very long periods of time, the rate of rampancy was very low.

Physical Description


The Precursors were humanoid to a point, but bore a great resemblance to the human insect known as a moth.

Zeban
Zeban was the Precursor homeworld.
