Algeroth is the Apostle of War, and the master of the alien "science" known as necrotechnology. Necrotechnology centers around the reanimation of dead organic tissue, and the modification of living tissue, fused with mechanical parts and electronic enhancements. This technology is used for the creation of weapons used not only by the forces of Algeroth, but by those of the other Apostles as well, and also for the creation of the core troops of the Dark Legion. Vehicles created with the use of necrotechnology are often "alive" in a sense, blurring the distinction between creature and vehicle.

Some of the creatures in Algeroth's forces can also be found in the service of the other Dark Apostles, as Algeroth trades his creations for boons from his "siblings". Thus, Algeroth is most associated with the Dark Legion, and the emblem of the Dark Legion is synonymous with his own rune.

The symbol of Algeroth is often referred to as a "dagger", though some refer to it as the "Cross of Algeroth", and others have surmised that it somehow represents a skull in abstract, or Algeroth's own face.

Powers of Algeroth

The powers of the Dark Symmetry employed by Algeroth and his spellcasting minions (of which there are relatively few) are primarily focused on raw destructive power, or the ability to encourage underlings to engage in mindless frenzied bloodshed.

Nazguls

When Mutants (of the devilcat, dog-man, kitsune and rat variety) are slain by forces of the Dark Legion and then are "recruited", they are thrown in with the rest of the Undead Legionnaires. However, on rare occasion, one may be captured and mutated into a slightly different version of a Necromutant, Centurion or other more familiar creature.

Nazguls, however, are a creation of Algeroth specifically created from captured dog-men. As part of the corruption process, their forms are twisted to look more feral and beast-like, standing upon digitigrade legs, and often given mechanical prosthetics for their forearms, with their faces permanently masked. These creatures are basically a variation on the Necromutant, sometimes given command of squads of Undead Legionnaires, or others of their "kind", with a tendency to focus on melee combat. They still retain their natural abilities of tracking and heightened senses, allowing them to pursue and hunt down human prey.

Gomorrians

The origin for this creature is still unknown, and it may well be entirely a creation of the Tekrons. These beasts look remotely like minotaurs of ancient myth, with quasi-humanoid, muscular and hunch-backed bodies, big stony fists, and digitigrade legs terminating in cloven hooves. Their muzzles are fused into cybernetically attached gas filters, and their sunken eyes glow balefully. Their thick, leathery hides are a deep blue fading to gristle-y white around the knuckles and joints. Most odd of all, however, is that they have two shoulder-mounted "gatling gun" weapons implanted into their backs, with a cord that leads to a thumb-switch operated trigger grip operated by hand. In the off-hand, the Gomorrian carries a massive hammer or other bludgeon.

At least one of these creatures has been spotted on Dark Eden, though it would be probable that the Dark Legion may have use for them elsewhere as well.

Carnal Harvesters

This creature looks like an over-muscled green satyr-like creature with its face typically covered by a stylized hockey mask. These creatures are typically armed with ranged weapons, and little is known of them, other than that they typically pause after a battle to devour the dead and wounded.

Ezoghouls

These creatures are undeniably alien. They resemble enormous centaurs, perhaps twelve feet tall, that gallop upon thundering hooves, and have heads that have been described as looking faintly equine or perhaps draconic. They are typically pale in color, either looking as if they have pale skin draped over a skeletal frame, or else covered with chitinous plates.

From the back of the upper "humanoid" body of an Ezoghoul sprouts two bony spines that vaguely resemble "wings" ... and, oddly enough, these structures are often found on the backs of creatures in the service of Muawijhe, even though Ezoghouls are strongly identified with Algeroth. Roughly one in four Ezoghouls is actually able to fly, using some sort of levitation that is somehow associated with these "wings". It has been surmised that these structures may act as a dark equivalent to the Power Stabilizers employed by the Brotherhood.

Ezoghouls are typically armed with giant versions of the organic sword known to the Dark Legion as the Ashreketh, and the Blutarch hand-cannon -- sometimes permanently fused to the Ezoghoul's arm.

Ezoghouls do not breathe oxygen, and can only do so thanks to a symbiotic relationship with a fleshy creature that they put over their muzzles when outside of the Citadels. Inside the Citadels, Ezoghouls are kept in "corrals" where they are supplied with the alien gases of their homeworld.

Tekrons

Tekrons are the masters of Necrotechnology. Each Tekron is different in appearance, looking like he may have once been human, but now far beyond that, with a body that has been spliced with various replacement parts, mechanical or organic. Many Tekrons have replaced their legs with "tank treads" to support their typically sizeable girth. Tekrons operate the unholy factories of the Citadels, and design new weapons of war for Algeroth. Tekrons are virtually immortal, since they can replace body parts at will. It is believed that Tekrons are created from willing converts to the service of Algeroth.

Brass Apocalypts

These massive, misshapen, mostly mechanical humanoid constructs are uniquely fashioned by the Tekrons, usually created to serve as their personal bodyguards, though they are sometimes found in service to Ilian. Their faces are masks of brass, fashioned to resemble the skeletally grinning face of Algeroth himself, and their backs are masses of writhing worm-like tubes, pumping nutrients into their metal-encased heads. By Tekron standards, each of these creations is a work of art.

Pretorian Behemoths

These are ridiculously large versions of Pretorian Stalkers, huge enough to be able to gobble down a man, or toss one aside. Their armor is similar in appearance to the style of Pretorian Stalkers, but the Behemoth operates alone, and has more muscle and sinew than mechanical components, by appearances. Pretorian Behemoths have four muscular arms, and are typically each armed with a massive chain-halberd in one hand, and a "hand-cannon" in another. A Pretorian Behemoth has bright red skin, and is distinctive for a large metal icon of Algeroth rising from the top of its armor like some sort of banner. So far, these creatures have only been sighted on Mars ... and it's uncertain whether there are actually more than one, or whether this is a unique monster that has recently arisen.

Nepharites of Algeroth

Nepharites are the generals of the armies of the Apostles, many times looking like lesser copies of the Apostles themselves. Nepharites of Algeroth have bodies that are an amalgam of flesh and metal and unknown other materials. Lesser Nepharites, given to commanding troops on the battlefields, tend to look more or less uniform -- tall, muscular humanoids that might be armed with any number of weapons of dark technology, but most often a chain-halberd weapon known as the "Azogar", or the organic sword known as the "Ashreketh". Their skin is typically bright red, their faces demonic with bared gums and sharp fangs, possessing bald heads and three long straight horns that extend from the top and each side of the head.

Higher-up Nepharites vary far more greatly in appearance. One of the most famous Nepharites, for instance, Alakhai, has blue skin with tattoos here and there on his hide. His servant, the Nepharite Magus Valpurgius, almost looks like a glorified Undead Legionnaire, with a skeletal face and yellow-orange skin, adorned in elaborate robes and decorative armor.

Some Nepharites seem more focused on raw combat ability, while others, referred to as "Nepharite Magi", are focused on the magical powers of the Dark Symmetry.

Nepharites are believed to be immortal -- Alakhai, after all, has been around since the first incursion of the Dark Legion into human space. Some of the Nepharites are believed to have once been human, while others (such as Alakhai) are believed to have been once been members of alien races previously conquered by the Dark Legion. One of the most infamous Nepharites of Algeroth, the revolting "Nepharite Queen" Golgotha, is held by some legends to have once been an exceptionally beautiful Valkyrie Vestal who was corrupted by the Darkness.

There are many cases where a Nepharite has been supposedly slain, and then the Nepharite appears again with a new (and sometimes slightly modified) body, though there is typically a long delay before this happens, perhaps suggesting that it takes time for the Nepharite to "regenerate". Unlike most creatures of the Dark Legion, however, the body of a Nepharite does not dissolve when it is slain. There are some legendary human warriors who have taken the three-horned skulls of (lesser) Nepharites as grim trophies of their achievements.
