Ogroid

Ogroids, known to themselves as Goroans, are a Chaos-affiliated race introduced in Age of Sigmar. As you can tell from their name, they're vaguely like ogres.

Formerly part of the Grand Alliance of Destruction, the Ogroids rose up in rebellion against Gorkamorka. When they inevitably got their asses kicked for trying to fight one of the strongest gods out there, they turned to Chaos to aid them. Their begging for aid offended Gorkamorka even more, and he lead his followers on a genocidal campaign that ensured that only those Ogroids who fled to the most chaos corrupted wastelands survived.

Despite their savage appearance, Ogroids are actually very intelligent creatures who can become highly skilled warriors or studious wizards. However, despite their pretensions of sophistication, if they get wounded in battle they fly into a berserk rage that shows their true bestial nature.

Ogroid Thaumaturges

The first Ogroid model released, Ogroid Thaumaturges are sorcerers dedicated to Tzeentch, and the combination of arcane prowess and brute physical strength makes them a force to be reckoned with. They are said to know more of the secrets of wyrdflame than all but the most accomplished spellcasters, making them particularly favoured by the pyromaniacs of the Pyrofane Cult. Some Thaumaturges lead their own covens of Tzaangors, while others act as bodyguards for the Gaunt Summoners.

Ogroid Myrmidons

The masters of the fighting pits of the Eightpoints, the Ogroid Myrmidons wield spear and shield, and carve magic runes onto their flesh to further enhance their fighting prowess. The various warbands of the Eightpoints are eager to fight under the gaze of a Myrmidon, and many congregate to their side in battle in order to impress them.

Ogroid Theridons

A new Ogroid troops unit revealed by leaks. Seem to be actual Shock Troop soldiers of the Ogroids, whereas Myrmidons are Gladiators for the amusement of Archaon.
