Garithos

Garithos was the Grand Marshal leader of remnants of the Kingdom of Lordaeron following its downfall during the Third War, and also de-facto leader of Alliance forces in Lordaeron, the New Alliance. Even in the situation the Alliance was facing after the Third War in Lordaeron, the Grand Marshal was very disdainful of non-human races of the Alliance, however, he cooperated temporarily with the undead that would eventually become known as the Forsaken.

New Alliance
Garithos was a survivor of the Scourge's rampage across Lordaeron, and he recruited what forces he could muster to fight the Scourge. Later, the healthiest blood elves led by Kael'thas Sunstrider, the elven prince of the ruined Quel'Thalas, joined him. Although the army was formed, Garithos was terribly racist and did not enjoy having to work with the blood elves or dwarves. And his belief was that the Alliance should never have accepted the elves in the first place, so Garithos dealt with his racist beliefs by putting those races to work at menial tasks.

Retake and defense of Dalaran
Garithos and his forces managed to retake Dalaran from the Scourge, and used it as their base. Later, Garithos gave Kael'thas the job of overseeing a caravan of supplies being ushered out of ruined villages, though Kael completed the mission, he wanted his people on the front lines with Garithos's main forces.

While they were in Dalaran, Garithos' scouting parties discovered a large undead strike force advancing through Silverpine Forest to attempt to retake Dalaran. Before Garithos left to push back the advancing scourge from the south, he informed Kael'thas that he and his bretheren would not accompany them on the front lines, and instead would be tasked with fixing the nearby observatories to watch for scourge flanks from the west, much to Kael's dismay.

Kael'thas performed his duties to the best of his abilities, but he had to accept the help of Lady Vashj and the Naga. When word of this reached Garithos, he immediately went to Kael and reprimanded him for consorting with the snake-people. Due to his racism, he didn't trust the elves as it stood, and believed the elves might betray his army.

The observatories repaired by the Alliance Remnants discovered that the undead strikeforce was coming from the west. Garithos returned to the front and left Kael'thas awaiting orders. Then, an emissary sent by Garithos informed Kael'thas that he had to engage the strikeforce from the west, but also recalled all support, cavalry, and siege units to the southern front, leaving Kael with only his blood elven troops.

Garithos defeated the undead in the southern front easily with the forces he had amassed. However, Kael was surely to be defeated, and would have been, had he not accepted another offer from Vashj and her Naga to aid in the destruction of the western Scourge forces.

Garithos returned and saw the naga leaving the scene. His racist fueled words said that this was the proof he was waiting for to execute Kael and his Blood Elves. He arrested Kael and his servitors and locked them in the Dalaran dungeons to await their execution, under the guard of Kassan. But soon Garithos heard that Kael had escaped with Vashj's help and were fleeing through a mystic portal. Garithos sent his men, armed with explosives, to destroy the portal, but the elven engineers Kael had freed used their knowledge to construct strategic defense systems. Kael and Vashj defended the portal and eventually fled themselves.

Mind controlled
Garithos, though furious, turned his attention back to the advancing undead. He pushed them back into Plaguelands, but was soon faced with the dreadlords, Detheroc and Balnazzar. Detheroc's powers of mental domination made quick slaves of Garithos and his men. The human served as Detheroc and Balnazzar's pet for some time until they were attacked by Sylvanas and Varimathras. Sylvanas slew Detheroc and Garithos was freed from his bondage. Garithos was asked to join Sylvanas in the final attack on Balnazzar and he agreed, so long as Lordaeron was left to him. The banshee agreed - but secretly had no intention of keeping her word.

Death
Sylvanas launched a two-pronged attack on the Capital, with Garithos attacking from the rear as she and Varimathras attacked from the front. But as the battle commenced, Garithos received word that the dwarven reinforcements had gotten lost in the wilderness. Garithos, annoyed at the dwarves, quickly left to find them, and brought them back to his base.

With the dwarves' help, the three allies were quick to dispatch Balnazzar's forces, and came upon him in the aftermath. Garithos watched as Sylvanas ordered Varimathras to kill Balnazzar. Despite their laws, which forbade the killing of another nathrezim, Varimathras did so. Garithos was lightly amused, but quickly changed his mood and ordered the duo to leave his land. Instead, however, Sylvanas ordered Varimathras to kill Garithos himself. Varimathras happily complied and casted Rain of Fire on Garithos, who was cannibalized by ghouls moments later.

Kingdom
Although Garithos lived in the continent of Lordaeron and one of his gag quotes is "In memory of Terenas", he has the Stormwind banner in his shield. As there is no concrete information, it is unknown what his kingdom is.

A possible explanation could be that he was once from Stormwind but chose to remain at Lordaeron after the Second War.

Quotes
GARITHOS: ''You are late, Prince Kael'thas. I thought you elves prided yourselves on punctuality.''

KAEL: ''It could not be helped, Lord Garithos. We ran into a group of night elves from across the sea, and --''

GARITHOS: ''I am not interested in your fanciful excuses! You elves are here to serve the Alliance: thus, you will obey my commands to the letter! Is that clear?''

KAEL: Yes, Lord Garithos.

GARITHOS: ''Now, the undead have begun a new offensive to retake Dalaran. Their primary strike force marches south through Silverpine, but we managed to halt its advance at the base of the mountains.''

KAEL: ''My men are ready to fight, milord! When shall we leave for the front? ''

GARITHOS: ''We will be leaving immediately. But, your people will be staying here. Our scouts report that a second strike force may be heading this way from the east. I need you to repair the outlying observatories so that we can monitor that region.''

KAEL: ''But, milord, we are warriors, not--'

GARITHOS: ''You have your orders, Prince Kael'thas. I trust your elven ears heard them clearly enough. Move out!''

(Garithos left)

KAEL: ''Insolent son of a... Let's get this over with!''

"I never trusted you vainglorious elves. It was a mistake to accept you into the Alliance in the first place.  Now at long last, you'll be dealt with appropriately.  Take them away!"

LAST WORDS:

GARITHOS (to Sylvanas and Varimathras): ''There, your business is done. Now, I want you wretched animals out of my city before I--''

SYLVANAS: Kill him, too.

VARIMATHRAS: Gladly.

(Varimathras casts Rain of Fire on Garithos killing him)
