Editing Mourning Sons (section)

==Enemies and Hostile relationships==
'''Chaos and the <s>Alpha Legion'''</s>{{BLAM}} {{BLAM|HERESY!!! No such Chaos Legion exists!! How many times I'm going to have to execute people for spreading this!?}}

The Alpha Legion is believed to be responsible for Innaculaba's devastation and the Sons target them and other Chaos Forces. Thanks to their mutation and abilities, the marines are capable of identifying those in league with Chaos. Incredibly useful when fighting Tzeentchian followers.

'''Inquisition'''

The Mourning Sons, due to being of the 21st founding, are suspected by some in the Imperium. The Inquisition is one of those organizations.

Due to their origin, they are distrusted by them. Partially because of their mutation, and partially because of the Innaculaba incident. Not to mention that one of the previous Chapter Masters slew a Inquisitor, though it was proven by the Chapter that the aforementioned Inquisitor was in league with Chaos Forces that were responsible for a system-wide Chaos incursion.
