A Tabletop role playing game that I have liked for a number of years. So I decided to make an RP for it. I will not participate in the RP itself, but I will provide and approve the storyline to make it interesting for everyone else. I will talk in the RP using NPC's

Space Marine Honour Guard (A Space Marine Honour Guard is a unit made of the best soldiers a chapter has to offer. Honour guards are two extremes, solemn and taciturn at peace but ferocious and unyielding in combat. They have achieved all awards and honours that a marine can, which puts them in a position of unrivalled knowledge. Often their knowledge outstrips the captains of a company but to offer open advice would be to undermine the position of the captain. To this end, any advice given by an honour guard carries a lot of weight within the command circle as well as among the rank and file. Even Chapter Masters have been known to seek advice from honour guards.)

Often the armour of a Raptor is modified with amplifiers and vox casters to emit terrifying sounds used to disorient their enemies, making them easier prey.)
Dark Apostle (In battle they are skilled demagogues, able to exhort followers to greater acts of bravery and depravity - enemy commanders have often found out to their cost that the only way to truly blunt an attack by such fanatics is to either remove the Apostle)
Berzerker (Driven by bloodlust, their only purpose is to kill and destroy their enemies in the name of Khorne. Eschewing long ranged weaponry, Berzerkers make almost exclusive use of close combat weapons, in particular the chainaxe.
