A detailed, chapter by chapter summary of The Hero of Ages.
Prologue
From the very start the process of Hemalurgy is revealed. Marsh basks in the pleasure of the fear of the Terrisman steward tied to the table. Below him is the Inquisitor they are about to create. For a moment, Marsh is able to regain control of his own mind, seeing the horry in what he is about to do, before Ruin completely subjugates him into continuing the task. He drives a brass spike through the heart of the Terrisman.
Chapter One
The book opens several months since Vin released Ruin from his prison within the Well. Fatren and his town are one of many that have been devastated by Ruin's malevolent horde of koloss and the killer mists. As they prepare for death having reports of an approaching koloss army they are greeted by a lone rider. This rider proves to be an Allomancer identifying himself as their emperor: Elend Venture.
At first Fatren considers Elend to be lying about who he is. Elend doesn't try to assume control of the town, but instead allows the people to assume that Fatren had called for his aid. Two armies are approaching the town but they will not arrive in time before the koloss so Elend offers to train the men in fighting koloss while he can.
The koloss army comes within sight, setting up camp a little distance from the bulwark of the town. Instead of mounting it for a defensive gambit, however, Elend convinces the town to charge the koloss camp with him while they're tired from marching. At first Elend leads the assault alone, but is shortly joined by Fatren and then the towns-people.
Chapter Two
TenSoon moves about his prison cell in the kandra Homeland, awaiting his sentence. His form lacks bones and sensory organs but he can feel the vibrations of his cell being opened, the pain of being lifted out by hooks. By the First Contract he should have a chance to state his defense: the guards give him a skull but begin to dissolve him with acid, twisting the words of the law.
Though TenSoon in his practise is able to form the necessary components to force speech and asks for judgement. By law, the guards have to grant him his request, though they urge him to accept death than speaking in a public forum and condemning himself to an eternity of suffering. Still, he persists, desiring something else than his defense.
Chapter Three
Leading the charge, Elend muses how Allomancy has given him the abilities to be in this position. His assumption about the koloss proves true as they're startled about the initial attack. This gives the assailants enough time to take down several hundred koloss before the blood frenzy kicks in. As the sounds of it alert Elend to its start he calls for the men to form up, simultaneously Soothing away their fear and Pushing on their emotions as he emboldens them. The battle drags on and Fatren loses his confidence, screaming about Elend leading them to die before Elend points at a speck in the sky.
Vin drops into the middle of the koloss, a storm of death and effortless acrobatics. Seeking out a thirteen foot koloss is all she needs to envigorate the fear in the surrounding koloss, killing it with a single boot to the head. Sparing a glance for Elend's force there are now several koloss fighting alongside the humans. Their plan was to instill fear in the koloss army and take control of them by the secret TenSoon had betrayed to her in Well of Ascension.Error en la cita: Etiqueta <ref> no válida; las referencias sin nombre deben tener contenido
The combination of Elend and Vin taking control of the koloss one by one pulls a Steel Inquisitor into the battle as she'd intended. Trying Kelsier's trick of wrenching out the spike in its back Vin finds a metal plate protecting that particular weakness of the Inquisitor's. Soon, Elend joins Vin's struggle as they move the fight to the top of a hill, away from the koloss. They struggle against the Inquisitor's experience but Vin manages to take control of a nearby koloss to kill the Inquisitor moments before it had a chance to kill Elend.
