Halo Forerunner Average Combat Skin Model

The Guardians of the Mantle.

"We are Forerunners, guardians of all that exists. The roots of the galaxy have grown deep under our careful tending. Where there is life, the wisdom of our countless generations has saturated the soil. Our strength is a luminous sun towards which all intelligence blossoms and the impervious shelter beneath which it has prospered." ~ Ur-Didact


The Forerunners are an ancient race from the Halo series, most notably the Novel series.

They were "seeded" by The Precursors in the planet Ghibalb, their civilization quickly rose in technological prowess and eventually gained interstellar travel and the ability to colonize other worlds, their home world was completely destroyed after an accident with Stellar engineering, which left them with huge ambitions in mega-engineering for millennia.

They started creating "Mega-structures" like their new capital Maethrillian & their "Cities" (Artificial Planets), created cures for hundreds of diseases, helped other civilizations, etc... but due to their arrogance they later started massive subjugation on planets all over the Milky Way Galaxy, horrendous experiments with other Civilization and the destruction of Stellar bodies and planets, which made The Precursors change their opinion on giving them The Mantle of Responsibility and gave It to the Humans, they in a moment of enragement decided to kill The Precursors and enter a war against the Humans, ultimately winning this war and reversing them to Neanderthals.

Though thriving for millions of years and achieving extraordinary technological feats, the Forerunners eventually fell prey to the horrific parasite known as The Flood. Their efforts to contain the parasite culminated with the activation of the Halo Array, eliminating all sentient species in the galaxy.

Long after their civilization's downfall, they are revered as gods by the Covenant, whom also base much of their technology from pieces of Forerunner technology.

Attack Potency: Human level (Comparable to normal Humans), Street level to City level with Personal Forerunner Armor (Their weakest guns were stronger than the standard Real Life Human Weaponry and use Ionization Technologies, they were capable of defeating enemies that survived 30 Megaton Bombs) | Building level physically (Promethean Swords are easily capable of Ionizing Spartans), Room level with Most Weaponry (Their standard weaponry is capable of Ionizing Spartans when they have deal enough damage), Building level to City Block level with Heavy Weaponry (Weapons like the Scattershot can easily Ionize Spartans, the Incineration Canon can ionize Hunters.) | At least Room level to Continent level with vehicles and mechs (Phaetons are armed with plasma cannons and incineration cannons, Seekers and Battle Sphinxes can wipe out cities spanning worlds and level continents) | Multi-Continent level to Solar System level with Starship Weaponry and Siege Equipment (The Mantle's Aproach that isn't fully suited for Combat purposes has a Ion Canon that buckles Continent plates, their Ships were capable of triggering a Supernova with "Stellar Colapse," and Forerunner Siege Weapons are capable of destroying planets.) | Varies, Moon level to Star level (The famous Halos are the diameter of 10,000 km, they were able to build "Cities", Planet-sized structures, the Ark Installations were the size of 32 Planets, some of their structures employ complex geometric shapes that appear to operate in dimensions higher than human understanding can comprehend, and they managed to make dyson spheres 2 AU in diameter), At least Galaxy level with the Axis of Galaxies (They were capable of Manipulating all of the Milky Way Galaxy at their pleasure.)

Type of Faction: Caste-based empire

Era: Prehistoric times

Times of Stability:

Times of Turmoil: 97,495 BCE to 97,445 BCE (Turning point of Forerunner-Flood War)

Holdings: At least 3,000,000 fertile worlds, thousands of megastructures, overall influence and dominance over the galaxy

Power Source: Vacuum Energy

Industrial Capacity: Extremely high. Shield Worlds such as Onyx can produce Onyx Sentinels in seconds and make swarms in the billions. Designer Seeds can build ships at a rate which overwhelms superhuman Forerunner eyesight. They can produce 10,000 km halo rings in 3 months from the Ark when not mediated
