Shadowspawn

In the world of the Wheel of Time series by Robert Jordan, Shadowspawn include a number of species, with varying levels of sentience, that have been created by the Dark One or other agents of the Shadow.

Trollocs were created by Aginor during the War of Shadow, one of the leading biologists of the Age of Legends, by crossbreeding human and animal stock. They are able to interbreed with humans, however the offspring are usually stillborn or do not live long. Trollocs are generally bipedal and humanoid, often with both human and animal features: human eyes but an eagle's beak, for instance, or a bear's paws and claws. They are huge in stature and extremely vicious. They are the basic shock troops of the Shadow.

Trollocs are credited with being able to see better than a man in the dark, however they can be blinded by bright lights. Trollocs are also able to track by scent or sound, and kill for the pleasure of killing.

Trollocs are omnivorous and will eat any kind of meat. They are routinely fed captives taken during battles with humans, which are cooked in large cooking pots. If there are no prisoners then lower-ranking Darkfriends are sometimes fed to the Trollocs instead. Trollocs are known to be lazy and this is shown when Rand al'Thor and Loial sneak past a Trolloc guard in The Great Hunt and reclaim the Horn of Valere from Padan Fain.

Unlike other creatures of the Shadow, Trollocs are social animals and form into clan-like bands, such as Al'ghol (Ghoul), Dhai'mon (Demon), Ghar'ghael (Gargoyle), Ahf'frait (Efreet), Bhan'sheen (Banshee), Dha'vol (Devil), Dhjin'nen (Djinn), Ghob'hlin (Goblin), Ghraem'lan (Gremlin), Ko'bal (Kobold), Kno'mon (Gnome), and Gho'hlem (Golem). Only male Trollocs are allowed to participate in raiding parties. Females are cloistered and remain in the Trolloc camps.

Some trollocs are capable of rudimentary human speech, but usually they converse amongst themselves in their own guttural tongue. Trollocs also have a written script for their language, in the form of angular runes. One trolloc, Narg, spoke to Rand al'Thor in his home in "The Eye of the World".

Trollocs are commanded by the Myrddraal, also known as Halfmen, the Eyeless, Shadowmen, Lurk and Fade. Their command of Trollocs began when the Age of Legends ended and the Forsaken were bound. During the Trolloc Wars, they led the trollocs in battle under the Dreadlords.

The weapons of Trollocs are made at the forges in the valley of Thakan'dar. Some of these weapons leave that place with a stain of evil in the metal. These blades can create wounds that will not heal or illnesses that medicine cannot mend. The weapons they use are often crude and cruel, something which reflect their brutish and war like nature.
