Ok, updated with new art (Thanks Brother Arkley!!!) and updated fluff to name the Ultima Founding properly. We still do not know how Primaris Chapters operate... so I am desperately waiting to find out so I can determine how this chapter will organize its forces.
I do know that I want to keep them fleet-based and not holding dominion over a world. These guys will replace losses while on campaign.
I also want to accurately show that this chapter is still very new... and they are eager to earn the respect and acknowledgement of not only Lord Guilliman (their creator), but also the older Chapters of Dorn's Legacy. Of course this is 40k, and that could be a detrimental thing... its how the Iron Warriors Legion started and we all know how that ended up for them. So these guys rush head first into battle... and are prepared to pay any price for victory. This could garner the ire of those they wish to impress. All just spit-balls at this stage.
Hopefully we get more info about the updated setting and then I can really take off. I am still unsure how to approach my Characters, as I am not clear if they were grown in a vat on Mars... or could they possibly be Primaris-Upgraded Marines from another Chapter. That could be fun.
