Hierax

Hierax proposes the Second Destroyers as a swift answer to the ork concentration on Thoas. Guilliman refuses the destruction and contamination that would follow. The dispute concerns necessity, but the decision to appoint Iasus over him also wounds his standing within the Twenty-Second.

He watches the campaign with a mixture of responsibility and resentment. His wish to demonstrate the Destroyers’ value does not remove his concern for the Chapter’s soldiers. Later, his inference that the underground military installation may conceal a weapons cache provides information Guilliman can use. The authorised deployment changes his formation’s role. Hierax should not be reduced to the officer who disagreed with the primarch: he is a case in which reforming authority must still recognise the knowledge held by specialists whose outlook it questions.
