Editing Brennus (section)

===The Hektor Heresy===

News of the Heresy didn't reach Brennus for some days until it began, by which time he and the majority of his Legion had gathered in orbit around Alessia to both celebrate the completion of a campaign and to recruit once more. When news finally did arrive, five of the twelve tribes immediately departed, leaving no notice or explanation as to their intentions. As word spread, it became clear that Ferdiad--who proclaimed himself leader of these rebelling tribes--had thrown his lot in with the Archtraitor. Thereafter, six of the remaining tribes left, with a course bound for Terra itself. Brennus himself remained on Alessia for a month more, brooding silently as he carefully considered his failure; the treason of his sons. He did eventually stir himself, decidedly burning Alessia before following his loyalist sons towards Terra.

The majority of the fighting the Thunder Kings did during the Heresy took place in the Sol system, specifically in orbit around Jupiter and Saturn. The Jovian and Saturnian fronts had begun before the first fighting took place on Mars and Terra, and control of them was assumed by the Thunder Kings once they arrived. It was characterized by several pitched space battles and desperate engagements across the surface of Jupiter's and Saturn's rocky moons. A number of precious archaeotech stations and refineries were lost to Black Augur spite, and the eventual arrival of the Eternal Zealots forced the Thunder Kings onto the defensive. Brennus did his best to keep the front together, and managed to keep the Voidwatcher and Aubrey at bay. The fighting would eventually culminate in the 5th Battle of Titan, where the Void Angels arrived with nearly their entire Legion to relieve the Thunder Kings and decisively destroy the Eternal Zealots and Black Augur forces present.

With Hektor dead and the traitors fled, the Thunder Kings rapidly set out in pursuit of their traitorous brethren. The assistance of the Void Angels was appreciated in this matter, and Brennus took to this particular task with a zeal it is said he rarely ever exhibited.
