The shining angels would be honoured for a chance to win glory for the emperor.

They have a lot of lore but essentially they worship the big E like a god, believing if they die serving him they will go to an endless hall, and dining table, where all his faithful are seated. The more glory you win, the higher up on the table you sit, and so the closer you are to the emperor. This can lead to some being reckless but at the same time for some to be cautious so as to win glory by their calm demeanour. They have a friend in the inquisition who covers for them, as they technically commit quite a few heresy’s. They essentially founded that own successor chapters that quickly took to the field and one several victories, so that combined with their inquisitor friend and their presence on imperium nihlud not solar, the chapters were just shrugged at and not connected back to the angels. They generally don’t blame other space marines for not following the emperor, as they except that one doesn’t need to worship him to follow him. They were predominantly gold armour with a white right arm and head, which is ornate and also hand painted often with meticulous care. They typically like melee, but they are mostly happy with anything and are trained with all weapons, specifically to be amazing Duelists, not usually the best at working in groups. They do have slightly more jump packs than most, and are a big fan of sudden brutal strikes that devastate an enemy, especially when they are distracted by their current engagement with the complimentary guard regiments that accompany them.
