Battle for Chiralarus

The Battle for Chiralarus was a joint-Imperial castigation campaign carried out by the Jonmarines Space Marine Chapter alongside their allies from the Lamenters Chapter, the daemon-hunting Ordo Maellus the Grey Knights (the Chamber Militant of the Ordo Malleus) and the mysterious and legendary Legion of the Damned, against the Forces of Chaos on the world of Chiralarus. This was a major engagement of the much larger Asteralixian Campaigns.

History
The Chiralarus Expedition, carried out by the Fourth and Eighth Companies, on order of Jonavaux Asteralix, the Founder, was the Jonmarines' first significant expedition out of the Majoris.

Captain Kodral Advlak, at the head of a Taskforce comprised mainly of astartes of the Fourth Company, would set out on the Jonmarines' first expedition from both their homeworld, and their home system, in order to announce the creation of the Jonmarines through action, rather than Astropathic communications and messages. This would result in Advlak's involvement in the Battle for Chiralarus, and the first interaction between the Jonmarines and another element of the Imperium of Mankind, namely the Grey Knights. However, Advlak noted that the Knights' Captain Quirael Fyralis seemed to be unaware of the Jonmarines' status of being a successor of the Ultramarines chapter, but discarded this uncertainty as being result of the Jonmarines' unproven status. Moreover, Captain Advlak becomes the first Jonmarine save for Jonavaux Asteralix to add an enemy to the Liber Inimicus, the ' Book of Enemies ', namely the Red Corsairs themselves.

Kodral also notes the presence of two groups he calls the zheltyyiak, belyikoi i chernyyethian, ( ' the yellow, black and white ones ' in Lawsundan Old Tongue) and the Khodityia Pozhararik ( ' those that walk whilst on fire ' in Lawsundan Old Tongue), as detailed above. Later, shortly before the Defence of Lokus, Kodral would discover that the Lamenters, under Malakim Phoros’ command, made up the entirety of this first group, while a force known as the Legion of the Damned made up the second. While relations between Jonmarines and Lamenters has continued far beyond the Defence of Lokus, Jonmarine - Legion of the Damned relations have been literally non-existent since that point.

The Battle for Chiralarus has, however, immediate implications. Amazed at the Jonmarines’ decisive intervention into the battle, the authorities of Chiralarus’ orbital dockyards known as Port Chiral decide to swear an oath of fealty to the Jonmarines, ensuring the Founder’s scions that if any of their ships need the services provided by Port Chiral, they will be welcomed as liberators and allies.
