The Archons of Steel
Back-story: Rising from the ashes of the Infebel Wars (ask me later for details if you wish). The infamous "Korozain" grew out of his shell of darkness and revived the dying Guardians. He kept their technology but integrated his own Frost based tech. Founded Icesteel, (actually formed from a special form of ice and titanium steel is used as the core of the material (like the center of a round would be steel and the rest is the Titanium-Ice compound) The intentions of this people are to protect the weak and good. And purify the unholy and evil.
Archon - Leaders and psionic masters
Archangel - Warriors of the Brotherhood
Tempest - Armor and Air division
Soul - The Dark side of the Archons of Steel
Archangel Berserker - Wielding two blades(or a long blade an energy-shield), an Icesteel frame powered by psi energy, and signfigant health and endrance. These warriors are the bulk of the Archangel sect. Plentiful, and powerful.
Archangel Hailstormer - A fragile, but powerful ranged unit. Capable of taking out important key targets in one shot, or in great numbers, able to decimate entire armies.
Archangel Purger - Berserkers who want to use a ranged weapon, but also be on the front-lines. These troopers utilize Phase Technology and create projectiles capable of completely warping or flat out destroying nearly any material
Outcast Soul Reaper - Archangel's who have branched off from the direct link with the Primarch and keep to themselves. They are not Exiled, instead they are revered for their dark ways, but most do not choose this path because their loyalty would stay with the Soul Primarch. These units are masters of stealth and sheer power. They are not to be underestimated and should be approached with caution, even with sensors present..
Archon Mage - An adept (human with high psionic potential) who has just stepped into the doorway of being an Archon. They are generally very powerful in offense, support, or illusion type "spells". They normally do not wear a lot of armor, but their minds are their main protection.
Archon Spirit - Formed from 3 Archon Magi who release their souls into a ritual circle and spend anywhere from a few seconds to hours colliding personalities and energies. The dominant will be the most present, but the other two will still reside and act as a conscience to the dominant soul. Spirits are not easily destroyed or disconnected from each-other.
Archon Soul Ripper - These Archons are either masters of Soul Energy (also known as Dark Energy) and will literaly destroy the minds of their opponents. They usually equip themselves with light blades or nothing at all. They have also been known to manipulate space (and on VERY few occasions time).
Archon Magistrate - Adepts who have reached the peak of psionic potential, and the mantle of leadership. They are either officers in the field or commanders in the back. Their mental shielding is as hard to break as their will, and that varies upon the person. Normally only a master of one kind of spells. (Illusion, Manipulation, Support, Offense[holds many branches], Soul, or [in very few cases] Purity.
Tempest Soul Strider - A basic ranged anti-personnel strider that will effectively take out infantry with high-speed projectiles that corrode light to medium armor and dissolves flesh. These units are capable of moving quickly and are used mainly for hit and run/guerrilla tactics. They can also (with the right pilot) phase enemies out of combat or teleport (distances range based on pilots abilities).
Tempest Guardian - Named after the factions predecessors the Guardians. These mechanical striders are 3 legged walkers that will unleash hell on any enemy through powerful shielding, armor, and strong Anti-Armor weaponry. It has close range an artillery capabilities. Piloted by any human with a knack for machines, this walker is a good example of human-machine symbiosis.
Tempest Sentinel - Robotic units that are used mainly for battlefield support. These units are capable of salvaging destroyed Tempest units and creating fortifications(which are very durable) and manipulating the battlefield to their favor. They aren't very strong with just their Proton Beam, but with a few ranged units, their Phase Bubble (a bubble that allows projectiles out but not in) can allow a 5-unit force to wreak unspeakable havoc.
Tempest Overwatcher - Colossal Tempest constructs. Outfitted with twin Cryo-Lances capable of decimated infantry and temporarily disabling vehicles. Their height can allow them to attack some air units, but its height also allows it to be vulnerable to Anti Air attacks. They aren't as durable as Guardians, but they can take a beating. Also equipped with high class sensor allowing them to detect cloaked/hiding enemies.
Tempest Revenant - Large destructive war-machines crafted from the remains of Tempest and old Guardian remains. They are expensive and hard to make. They make an Overwatcher look the size of a regular infantry unit. They are not used in the battlefield unless it is direly needed, they are used to protect colonies and high-value bases/cities. They are large four legged walkers, that are outfitted with a main Particle Cannon, that will destroy structures with one shot, and break down anything on the molecular level. They also have dual - phase cannons on each leg, and on the bottom they have a high rate of fire FS-X400 (Frost-Shot 400rnds/min.) It is also known to transport masses of people/units.
Tempest Sky-Guard - The basic flying unit of the Tempest. A fast aerial unit with twin Frost-Shot cannons that fire quickly, but have low power. A squadron of 5 can decimate a platoon of infantry in no time flat but have a hard time dealing with armor and some air units (especially fighters that are faster than it). Usually used for recon of planets.
Tempest Sky-Breaker - The Tempest Sky-Breaker is the fighter of the Tempest Airforce. It takes down other aircraft quickly and efficiently with its quad Ice-Ripper cannons and dual Proto-Missile pods. They aren't as fast as Sky-Guards but their heavy shielding allows them to last long in an aerial dogfight.
Tempest Soul Ripper - Also called the Soul Corvette (due to its role and size) is the first orbital warship of the Tempest force. It utilizes Antimatter-Frost Cores. They slow down anything it hits, while ripping them apart.
Tempest Haven Cruiser - A large ship based on combat support in space. It can put up a large shield, capable of covering a mid-sized fleet, can warp whole fleets into slip-space and freeze (or at least slow) ship processes. It's main weapon is a Pure Icesteel Soul Shard that projects "Soul" energy and is purified, adding even more damage.
Tempest Nexus - The Capital ships of the Tempest fleet. They carry 16 attack drones (about the size of fighters) piloted inside the ship. It's main weapons consist of 8 Icesteel Flak-Batteries, quad Particle Beams (front and back) 3 Frost-Shot Cannons on each side, 4 Large Proto Missile Pods, and a "Frozen Decimator" Laser system. (The effect of the Soul Ripper but much more unstable and more powerful).
Still a slight work-in-progress.
