Brinlaw
Brinlaw was an Imperial tacticae, who was amongst the hundreds that aided the Primarch Dorn's efforts in planning the Imperial Palace's defenses, during the Siege of Terra.[1a]
History
Like the other tacticae, Brinlaw was considered to be amongst the Imperium's greatest strategic thinkers, in the age of the Horus Heresy. When the Siege of Terra began, the tacticae were located in the Imperial Palace's Bhab Bastion and worked within the Bastion's Grand Borealis Strategium, which served as Dorn's main control room. They were initially safe there, as the Bastion was located in the Inner Palace and was far from the fighting. Eventually though, despite Dorn's best efforts, the forces of the traitorous Warmaster Horus reached the Inner Palace and soon began attacking the Bhab Bastion's walls.[1a]
Despite this, the tacticae and other Imperials there continued their work and did not stop, even as the Bhab Bastion was invaded. It was only as the Traitors neared the Grand Borealis Strategium, that it began to be evacuated for the safety of the Imperial Palace's Sanctum Imperialis. However, this was done too late and many within the Strategium were killed by the Traitors before they could escape. Its not known, though, if Brinlaw died within the Bhab Bastion[1a] or was among the few survivors who managed to reach the Palace's Sanctum Imperialis, before the Eternity Gate was closed.[1b]
