Okay, then let's go with probably my favorite story-that-needs-to-be-adapted-by-HBO present in the games: Potema the Wolf Queen and the War of the Red Diamond.

Let's set the stage: We begin in 3E 63, with the future emperor Pelagius II. After being widowed and left with two children from his first marriage, the emperor travels to Camlorn in High Rock, and comes to court with the Princess Quintilla. He arrives to find the castle besieged by a werewolf, and aids the princess in defeating the beast. The princess soul traps the werewolf into a gemstone, which Pelagius later fashions into a ring. He proposes to Quintilla, who gives birth to Potema shortly thereafter. It is said, however, that the soul of the beast they slayed stayed with the couple, and made itself present in their firstborn daughter, a child who was described by her grandfather Uriel II as being "like a she-wolf about ready to pounce."

Potema was eventually married off (at the age of 14) to the king of Solitude in Skyrim, where she grew and manipulated those in her husband's court. She staged circumstances so that the child of her husband's - Mantiarco's - previous marriage would be deemed an illegitimate bastard. After numerous miscarriages, Potema eventually gave birth to a child named Uriel, who was now perfectly positioned to become king of Solitude and eventually vy for the Ruby Throne in Cyrodiil. Years pass, Pelagius II and dies, and his children convene at the coronation of the new emperor, one of Pelagius' other children, Antiochus. Mantiarcho passed away shortly thereafter, and Uriel came to rule as King of Solitude alongside his mother.

In the Imperial City, Potema meets with Quintilla, who gives a gift meant for Uriel when he comes of age: a necklace carrying the gemstone of the werewolf's soul, enchanted with Illusory magic to charm those the wearer speaks to. Potema meets with Antiochus in an attempt to blackmail him into abdicating his right to the throne. Though she failed to shake him, she spent the next several months manipulating the Mages Guild, Psijjic Order, and the Maomer of Pyandonea in an attempt to leverage a planned invasion to weasel millions in gold into her own coffers to finance a coup against her brother, who had already taken the throne as emperor.

Antiochus was a debaucherous emperor, whose lust is perhaps only eclipsed by The Remanada in its perversity. The Empire was left with Kintyra II as a claim to the throne after Antiochus mysteriously died after a visitation by his nephew, Uriel. Potema visited the Elder Council and declared that Kintyra was, in fact, a bastard and attempted to leverage her charm to convince the Council to appoint her own son as emperor. Her efforts were in vain, and Kintyra II rose as Empress in 3E 120.

In her years of planning and preparation, Potema had acquired allies in the many disgruntled nobles of Skyrim, Morrowind and High Rock. Raising and army on three of Cyrodiil, Potema made to declare war to unseat Kintyra as Empress and install her son in her place. Kintyra moved her army into position near Glenpoint Castle in High Rock, planning to oversee the destruction of her aunt's forces personally after the insulting testimony she gave to the Elder Council.

Once again using her skill at blackmail and forgery, Potema convinced Kintyra's husband-to-be to evacuate the troops remaining in the Imperial City, ordering them to meet with Kintyra's forces in a week's time. Under cover of night, Potema's troops committed the mass assassination of Kintyra's forces, carving their way to her quarters where she was captured, presumably tortured, and summarily executed while Uriel's armies marched on the now-undefended Imperial City. With this brutal coup complete, the remainder of the Empire turned against Potema. Her two half-brothers Magnus and Cephorus gathered their own armies and spent the next few years waging war against Potema and Uriel, fracturing the continent in a civil conflict not seen since the Interregnum.

Years pass, and Uriel is engaged in a battle with his uncle Cephorus in Hammerfell, while Potema staves off her half-brother Magnus' advances from Morrowind (which he has made by co-opting the Argonians into his cause). During the Battle of Ichidag in 3E 127, Uriel was captured by Cephorus' forces and transported to the city of Gilane, where he would await his eventual return to the Imperial City and supposed trial. However, as Potema stalled Magnus in the swamps in northern Morrowind, she hears word that Uriel's caravan was intercepted by an angry mob, and that he was burned alive. Cephorus was raised to the title of Emperor while Potema's army finished their rout of Magnus' forces.

With Uriel dead, the nations of the continent struck deals with the Cephorus emperorship to attain greater autonomy than was had under previous rule. Skyrim, High Rock, Hammerfell, the Summerset Isle, Valenwood, Black Marsh, and Morrowind all gained sovereignty. The War of the Red Diamond had ended, but Potema continued to fight against the forces slowly closing around her sphere of influence in Solitude.

With the death of her son, Potema fell into madness. The lands of Solitude became lands of death, as she summoned daedra to fight for her, reanimated the corpses of her enemies' soldiers to serve as her own army, and conversed with the wraiths, vampires, and other necromantic fiends. As Magnus' armies close around her, she escapes from her castle one last time and chances a meeting with her half-brother's son, Pelagius III. Her nephew does not recognize her, but she gives him a gift in the form of a necklace, one with the amber gemstone carrying the soul of a werewolf. However, the trinket no longer held its enchantment of charm. It had been replaced by Potema with an enchantment of poison, which would slowly sap the strength and wits of the wearer until they lost their minds.

Returning to her castle, Potema waited out the remaining month-long siege before dying in her sleep. Magnus granted stewardship of Solitude to his son, Pelagius III. Years would pass as Cephorus and Magnus eventually died, and the "eccentric" Pelagius III would eventually rise to the throne of Emperor.
