Exodus Cause (d100)

1-6

after coming to blows with the Imperial Inquisition for actions undermining their authority to aid other fellow Imperials, resulting in their excommunication

7-13

due to their habit of causing more collateral damage than the Imperium felt comfortable with.

14-20

after receiving secret commands from high-ranking Imperial Lords that demanded this chapter's secession from the Imperium, either for unspecified reasons or for a particular mission.

21-27

after their discovery and use of Chaos-tainted weapons. As soon as the Ordo Malleus found out, the chapter was exiled.

28-34

by dabbling in technologies beyond them and being declared Hereteks by the Mechanicus, who forced them out of the Imperium.

35-41

after becoming too friendly with a group of Xenos, even going so far as to collaborate with them. Excommunication came quickly once the Ordo Xenos found out.

42-48

after a long history of constant ridicule and undermining at the hands of other Imperial forces. In the face of numerous lost glories and dwindling reputation, the frustrated chapter decided they had suffered enough under the Imperium and struck off on their own.

49-55

after a number of unfortnuate political choices and affiliations. Victims of the fickle nature of politics, the chapter were declared traitors and forced to flee the Imperium.

56-62

thanks to their radical deviations from the Codex Astartes, causing more adherent chapters to lack trust in them.

63-69

due to their disillusionment with the Imperium, seeing it as a perversion of the Emperor's will. Deeming its festering bureaucracy beyond redemption, the chapter rebelled in order to try and stay true to the Emperor.

70-76

After their fear of their own extinction drove them to commit a cowardly, horrible act in the hopes of their own salvation.

77-83

long before their actual exile; whether by their founders, other parties in the Imperium or fate itself, such an excommunication was inevetable.

84-90

after their gene-seed was found to be contaminated beyond acceptable limits, resulting in their expulsion.

91-97

after a single champion within the chapter's ranks led his brethren down the path of excommunication through his philosophies and ideals.

98-100

due to their lust for high adventure. Seeing the Imperium as a restrictive entity only holding them back, the chapter left on their own accord to forge their own path.
