The Enlightenment

The Enlightenment is the name of the period of the early history of the as-yet unnamed Ashen Apostles Space Marine Chapter when they forged their reputation as a zealous and notable adherents of the Imperial Cult, bringing the light of the Emperor to the darkest corners of the galaxy.

Background
Following the event of the 21st Founding, the chapter, unnamed at the time, was sent to deal with a possible chaos cult growing on the planet of Ymittre II. Upon investigating the main hive of the planet, they discovered a large chaos cult within the hive. After this discovery, the chapter immediately began burning down all of the hive levels that had cult activity within them. After successfully destroying the cult by burning down approximately 24% of the Mid-Hive's levels, some of the Astartes within the chapter began preaching to the masses while still covered in the ash of the burned hive floors. While doing this, the hive's populace quickly began referring them as their "Ashen Apostles" bringing them into the light of the Emperor. During this, the new chapter began to take on the name, and spent a very large amount of time preaching to the denizens of the hive before leaving in their ships.

After cleansing Ymittre II, the Apostles began to visit the rest of the system's planets, searching for and cleansing any chaos corruption present and then spending very long periods of time preaching to the masses. This lead to the chapter being adored by the citizens they brought the Emperor's light to, yet it also brought the spite of the Inquisition, as they believed they believed the chapter to be lax in pursuing their goals. However, upon spending so much time extinguishing the heresy of chaos, some of the chapter began to find new goals in the light of different, much darker gods than the Emperor.
