Nalun campaign participation reward

As a result of the collective Imperial losses and Xenos treachery, Inquisitor Cole is dead. The Astartes present in Fates End for the event swear oaths of moment, and affix purity seals; a popular trophy for the Xenos defilers. 

You too can earn your purity seal for meritorious contribution to the campaign by either:

A) Participating in three phases of the campaign at any level.

or
B) Submitting an operation report that gets featured in the end of phase report. 

For extra credit, submit supplemental materials that go above and beyond. It can be anything really, play towards your strengths; a well-written narrative, creative photography, awesome terrain themed for that phase, etc.
