Originally from a thread on the official forums that has since been pruned, this is a list of the lore behind the various World of Warcraft realm names as of some time in early 2005.
Aggramar - Aggramar the Avenger: Vanir Titan of the Pantheon. Once Sargeras' lieutenant, Aggramar took over Sargeras' postition when his superior changes sides. Aggramar is now in charge of combatting the Burning Legion and eliminating demonic taint.

Alleria was a fabled Ranger for the Alliance during the Second War, but never realized fully just how dangerous the Orcs were until she saw the ruins of Quel'thalas, and searched for her family in what was left of it.
Alleria's thirst for vengeance caused her to create a cadre of Rangers who was solely dedicating to hunting down any free Orc left in Azeroth and eradicate them. Alleria's quest led her straight through the Dark Portal on the heels of Khadgar and the Bleeding Hollow Clan.
Alleria fought valiantly against the forces of Ner'zhul, but in the end, she knew the sacrifice she would have to make, and assisted in closing the Portal from Draenor, sacrificing her way home. Last heard, she was lost within the Twisting Nether.

"Having done battle with the Undead on many occasions, Orc warchief Thrall and Tauren chieftain Cairne Bloodhoof of the Horde were immediately suspicious of the Forsaken's motives. However, due to growing political tensions, the warriors acquiesced to a council of sages known as The Earthen Ring. The council argued that it was the Horde's duty to aid the Forsaken, who wrestled with inner demons just as the Orcs had for generations."

They were once again corrupted by the Pit Lord Mannoroth when faced with annihilation by Cenarius's army. He was the first to drink Mannoroth's blood. With their new chaotic powers, they killed Cenarius and defeated his army, but carried the taint of the Burning Legion. They were liberated when Grom Hellscream killed Mannoroth in an epic battle with Thrall. Hellscream charged Mannoroth and delivered a mortal wound to him, but Mannoroth took Hellscream with him to his death.

Hyjal - Mount Hyjal in northern Kalimdor, where the World Tree is located.
Icecrown - The Lich King's capital in Northrend, where the Frozen Throne is located.
Illidan - Illidan Stormrage, twin brother of Malfurion Stormrage. He was one of the greatest Night Elf sorcerers in the land. Before the first invasion of the Burning Legion, his brother convinced him to give up magic before the impending doom of the Burning Legion arrived, and with the help of Tyrande Whisperwind he did so for a while.
However, before Malfurion was ready to attack Azshara and her Highborne summoning the Burning Legion, he went and warned her in order to preserve the magic he is so addicted to. He collected some samples of the original Well of Eternity and escaped the great sundering. He gave some to the Highborne who later became High Elves. They used it to create the Sun Well to sustain their own magics. He used the other vials upon the top of Mount Hyjal after the great sundering to create a new well of Eternity. Without him, magic would have ceased to exist in the world.
He was binded and imprisoned in the earth by his brother for his betrayal, and the danger he posed. For 10,000 years he was imprisoned until Tyrande Whisperwind, against the wishes of Malfurion, freed him and asked for his assistance to defeat the Burning Legion. He agreed. He was duped by Arthas to consume the skull of Gul'Dan, a powerful artifact that enhanced his already formidable powers many times over, and kill the dreadlord Tichondrius. When he did this he sealed the defeat of the Burning Legion, both benefitting the Undead Scourge who did not want to be ruled over by Tichondrius or those over him, and everyone else that the Burning Legion threatened.
Afterwards he made a deal with Kil'Jaedan to destroy the Lich King for his betrayal of the Legion. This was the main focus of the Warcraft III: Frozen Throne expansion. He had a plan that was foiled by his own brother to destroy the Lich King, then went and hid in the Outlands to avoid Kil'Jaedan's wrath (but to no success). He again sought out to destroy the Frozen Throne, with the help of the Naga and Blood Elves set out an army to defeat them.

He is pursued by a band of hunters who work for a ruthless Elf named Dar'Khan. Dar'Khan wants the Sunwell, a lost source of Elven magic, and believes that Kalecgos knows its location. The story becomes more than just a series of fights and chases when Anveena and Kalecgos are joined by a female dragon who says she is Kalecgos' future mate, which creates a potential love triangle." He is in no way related to any form of breakfast brands.

As a result, Alterac was destroyed long before the Scourge arrived, and Lord Perenolde was executed as a traitor. A few years ago, his son, Aliden Perenolde, decided to try to restore power in Alterac. However, he is doing that through underhanded means. He currently leads the Syndicate in a misguided attempt to restore prestige to the Perenolde name.

They have the mentality that if you're not with them, you're against them. If you're not with the Scarlet Crusade, you must carry the taint of the scourge and be removed. Therefore they will attack almost any other faction on sight, believing them to be Scourge assassins or otherwise a threat.

Shadowsong - Maiev Shadowsong was the jailor of the night elf betrayer Illidan. For ten thousand years she guarded over Illidan's prison in the Barrow Den.
Illidan was released by Tyrande Whisperwind--against the wishes of Malfurion Stormrage--in order to assist in the Night Elves' fight against the Burning Legion. After Illidan made a pact with Kil'Jaedan, Maiev started hunting him down to imprison him once again. She followed Illidan to the tomb of Sargeras, where Illidan recovered the eye of Sargeras. His naga army nearly destroyed her army of watchers and she called for aid from Furion and his Night Elf army. Brother waged war against brother and Illidan fled to the Eastern Kingdoms where he would go to the ruined city of Dalaran to use the eye and channel a spell destroying the Frozen Throne.
Maiev and Tyrande hunted him there while Malfurion communned with the damaged lands of the Eastern Kingdoms. Tyrande made a last stand at a bridge, a sacrifice that saved Kael and his people along with Maeiv from the Undead Scourge. The bridge was destroyed and she fell downstream a river. She told Malfurion that she was torn to shreds in front of her very eyes, and consumed Malfurion with thoughts of vengeance against his brother.
Maiev's lie was soon uncovered however, and Illidan aided his brother Malfurion in Tyrande's rescue. In return Illidan was freed from his bondage, and he fled to the lands of Outland. Consumed by her desire for vengeance, Maiev followed Illidan blindly. She and her Watchers found Illidan by himself and captured him, but he was soon saved by the Naga and Blood Elves loyal to him. Defeated and left with a desire to get vengeance upon Illidan, her current location is not known.
Jarod Shadowsong is Maiev's younger brother. Jarod took over command of the Kaldorei armies after the death of both Lord Ravencrest and Lord Desdel Stareye in the War of the Ancients.
His leadership as well as diplomacy between the Kaldorei, Taurahe, Earthen and Furbolgs staved off the armies of the Burning Legion long enough for the Well of Eternity to be ruptured, throwing out the Burning Legion and effectively dismantling Kalimdor into the continents and islands known today.

In the novel Day of the Dragon, Nekros Skullcrusher is described an a former warrior who turned to magik(warlock) after losing his leg. In orc society this was too much of a handicap to attain and keep leadership. He did'nt know how to tap into the full power of the Demon Soul, and fantisized not only about being leader of his clan, but thought that he could be Warchief...if he could only figure out the Demon Soul.
