Gorkil

Gorkil the Goblin King was a chieftain in the service of Sauron. He was the king of all Goblin tribes and the Dark Lord used him to strenghten his grip upon his remaining forces that had been scattered in the North.

History
Gorkil had established his stronghold in a former outpost in the Ettenmoors that formerly belonged to the Witch-king of Angmar. From there he ruled over the Goblins, Spiders, Trolls and Giants that lived in the Misty Mountains and gathered them to him, eventually commanding a huge army.

Good Campaign
Due to his growing power in the North, Gloin and Glorfindel led an attack upon the stronghold and destroyed much of his army, before slaying the Goblin chieftain himself.

Evil Campaign
Gorkil joins the Corsairs of Umbar in the Grey Havens and has his army brought to shore by their warships. His forces create a main base, before he himself leads his army in slaying the Elven guards and destroying their structures with the help of their pirate comrades. With the Grey Havens in ruin, the Goblins leave and head for the Shire.

Wanting to settle scores right after the defeat of one of their old chieftains named Golfimbul, Gorkil leads the Goblins and their allies against the Hobbits and Men that aid them, while also destroying the four main seats of power in the Shire. After defeating them, the chieftain is confronted by Gríma Wormtongue who wanted to claim the land for himself. The servants of Sauron entered a civil war-state and infighting broke out between the Goblins warriors and the fighting Uruk-hai, until Gríma was slain and thus the Isengarders were forced to retreat, leaving the Shire to Gorkil.

After receiving word that Sauron has returned and Frodo Baggins had been slain, he is sent to lead the siege upon Rivendell. He brings forth a mighty army and joins forces with Drogoth the Dragon Lord in attacking the Elves. With the help of Mountain Giants, Gorkil destroys the Battle Towers and the front gate. After the legions storm in, the Mordor army arrives and the king gives control of the invasion to his master, becoming one of his lieutenants. The combined forces lay waste to the Hidden Vale and slay Elrond, Arwen, Glorfindel and the Fellowship of the Ring. As the city falls prey to his servants, the Dark Lord watches from above and gloats in his triumph.
