Summary for anyone who wants to jump in halfway through rather than reading through it all.
In short, I wanted to explore the idea of agency in questing, and the problems one might experience when experiencing the freedom of the quest format, yet also being bound by the constraints of the setting.
The quest follows Grok'mash of the Burning Blade, an aspiring Blademaster of his clan. The Burning Blade are the most scholarly of Orcs, and possess the unique martial tradition of the Blademaster. Grok is a prudent, but extremely honourable Orc, much concerned with impressing his father, Chief Neeru Fireblade, elevating the status of his clan, and becoming a Blademaster.
Grok begins the quest as a capable swordsman, and leaves the Valley of Trials along with several other orcs. Grok travels to a troll village to assist the people there in their various affairs. During this time Grok attacks a Kul Tiran garrison, killing many humans with the assistance of his Mok'nathal friend, Vark. While performing well, Grok is heavily wounded in his encounter, and in the aftermath swears blood-brotherhood with Vark. Having done some training and met Rexxar, Champion of the Horde, Grok begins some investigations into different magical traditions such as Shamanism, and subsequently leaves Sen'jin Village to travel to the Orcish capital, Orgrimmar. On his way, Grok rests at Razor Hill, an Orcish settlement, employing the secret arts of his clan to capture two elemental spirits of fire and earth.
In Orgrimmar, the Warchief of the Horde, Thrall, lures Grok to his throne room, attempting to influence the young orc. However, Grok's father arrives and Grok observes the intrigues and schemes that play between the Warchief and the Burning Blade. While in Orgrimmar, Grok resumes his place in his clan, but is warned by his father that unless he proves worthy he will be exiled. Grok seeks out a teacher of Shamanism, learning about the different cultural models of the practice, as well as finding a Blademaster, Akinos Steelclaw, to teach him further. Grok is eventually tasked with the death of the treacherous warlock, Darkstorm, and leads a small warband to attack the renegades.
While nagivating his father's high standards, the cultural issues within his people and confronting the genocidal history of the Orcs, Grok travels to Dreadmist Peak to learn from the elders of his clan, as well as to combat the Kolkar centaur tribe. Grok vigourously attacks the centaurs, who eventually rally at the urging of a shadowy figure, attacking Dreadmist peak with a large army. Grok leads the defence, slaughtering hundreds of the Kolkar while buying time for the warlocks of his clan to summon a demon to destroy the rest. However, the centaur too perform a great sacrifice and summon Forneus, Duke of the Inner Earth, a great elemental who destroys the mountain and almost all in the vicinity. Finally, the shadowy figure who rallied the centaur is revealed to be Jubei'thos, a supposedly dead Blademaster who kills Akinos, only for Grok's teacher to sacrifice himself to save Grok, ordering his student to hold honour above other virtues.
In the aftermath of Dreadmist, Grok and two other survivors pursue Forneus on his march toward Orgrimmar in the aftermath of the elemental's cataclysmic emergence. Grok attempts to distract the elemental and sacrifice himself to sate it's rage, but is unsuccessful, and is knocked unconsious.
Grok awakes in his family's residence, learning that Thrall was defeated by Forneus, who in turn was defeated by Grok's father, Neeru. Grok's father proudly presents him with an ancestral blade and confirms his place as heir of the clan. However, in an attempt to reduce the growing threat of the Burning Blade, the Warchief Thrall calls Grok before him, attempting to trap and publically denounce the Burning Blade as demon-worshipers. Grok, seeing through this attempt, claims the blame for various actions including the devastation of Orgrimmar due to Forneus' assault, and is exiled by Thrall.
Grok leaves Kalimdor at the head of a reinforced warband, with his father's blessing, travelling to Lordaeron to assist the Scarlet Crusade against the undead Scourge. During this time Grok meets and assists various human notables, including Tirion Fordring, Bolvar Fordragon, Katrana Prestor and Saiden Dathrohan, as well as witnessing the marvels of the Holy Light, as weilded by the Apostle, Fairnbanks. Proving himself in battle and diplomacy, Grok is sponsored by the Crusade and independantly seizes the stronghold of Andorhal, defeating the death knight, Marduk the Black, in a duel, as well as participating in the destruction of the lich, Araj the Summoner. Grok is confirmed to have gained the rank of Blademaster by the acclaim of two Blademasters in his warband.
During the Scarlet Crusade's further preparation, Grok accepts a commission to travel to the Arathi Highlands and deal with Orcish and Ogre clans there raiding the Crusade's supply lines. Grok attempts to mediate between the Stromic kingdom and the Orcs of Hammerfall while Vark subjugating the local Boulderfist ogres in a duel. Additionally, Grok utilises elementals in his battles with the bandits of the Syndicate and binds the powerful elemental spirit, Myzrael, to his service. This, along with other choices, confirms Grok's philosophy as a 'Dark Shaman', a cultural practice more aggressive and confrontation than some others among the Horde. Grok finally leaves Arathi with a much reinforced warband, having negociated a sort of ceasefire between the orcs and humans of the area.
Grok selects a chosen few to participate in the assault on Naxxramas, including the Black Dragon, Kalaran Windblade, and the Banshee Queen, Sylvannus Windrunner, as well as two Blademasters, Vark, and some others from his warband. Taking losses, Grok fights through the Dread Citidel and confronts Alexandros Mograine and the Four Horsemen of the Scourge. In an epic duel, Grok faces the Ashbringer in battle, but is killed. A strange pure fire revives the Blademaster and Grok shatters Mograine's sword, destroying the Death Knight.
In the aftermath of Naxxramas, Grok's warband swells with local orcs seeking adventure with such a prestigious and honourable warrior, while Grok receives the acclaim of the human nobles. Grok discusses his experiences with Tirion Fordring, concluding that he has touched the Holy Light, the first Orc to ever do so. Tirion advises him to conceal this matter to avoid confusion and debate around the issue while the Sourge is still a major enemy.
In a final task in Lordaeron Grok travels through the Alterac Mountains to seek out information on the orcs of that area, and specifically to learn more of Jubei'thos and why the elder blademaster attacked him previously. While naagivating Alterac Pass, Grok visits the Frostwolf orc clan, but is villanously attacked by their chief, Drek'thar. Grok fights his way free, killing Drek'thar's son, as well as summoning Myzrael to combat Lokholar the Ice Lord, an elemental ally of the Frostwolves. Grok is victorious in battle, exiling the remaining Frostwolves, with the fate of Drek'thar currently unknown.
Grok combats the bandits of the Syndicate in Alterac, defeating their army and allying with Bishop Karlus of Varnhold. Hearing of Orcish raiders in the north, Grok finds thousands of the Demonsword clan ready to attack Varnhold, and accepts the challenge of a duel from their chief, Haomarush Demonsword. Grok defeats Haomarush in a famous duel, once more using the Light in battle, and gaining the loyalty of the Demonsword clan.
While considering his options, Grok reflects on the pitiful position of many orcs in Lordaeron, and decides to accept an offer to become Constable of Alterac, the military commander of that region. With the new Queen Prestor occupied with matters in Stormwind and her marriage to Varian Wrynn, Grok is left as the most powerful figure in the kingdom, though in the unenviable position of becoming even more involved in the intriges and high politics of the Alliance.
