While everything don't have to make logical sense to the 20th century person, there should be some internal logic in the setting. Every time the GM has to explain things which: "that's simply how its writen" - is a sad day.

Out of the traitor legions, I'm most fond of the Night Lords and Alpha Legion. Both use cunning tactics and neither have great reverence for the chaos powers.

As for the rosarius, it can be a bit silly if it is just "electronics". But considering how 40k tech works, who's to say each one isn't built with "holy" rituals that bind the tech to the Emperor? Taking holy to mean "Emperor-powered psyker power".

The problem is if we start with that kind of explanation it would be logical that an untouchable can ignore the Rosarius of an enemy.

A fair point. Perhaps the rosarius' ability to distinguish between believers in the Emperor and His foes would be compromised. Or it works on different principles altogether.

Out of curiosity, can you site your source for the Night Lords having at least one daemon prince and/or possessed members?

While certainly not 100% authoritative, I checked out the Night Lords entry in the Lexicanum and it notes the Night Lords, as a whole, as being exceptionally proud of not being corrupted by Chaos and looking down on those who are corrupted.

Some other interesting facts:

• Unlike a number of other rebellious Primarchs, Curze never became a daemon prince.
• The Night Lords' geneseed is among the most pure geneseed in existence.
• After the Horus Heresy, the Night Lords did not retreat to the Eye of Terror.

I don't know enough about FFGs 40k RPG* games to make a truly educated guess, however, if Black Crusade doesn't provide rules for characters not looking to ascend/descend to daemonhood/chaos spawn, I would suspect you'd have a couple of options:

• Special rule them to neither gain corruption nor infamy; or to limit their effects; or to otherwise specially handle the two traits
• Handle them like normal Marines from Deathwatch
• Some combination of the two methods above

*Black Crusade is the first game in the line/genre/field to truly catch my interest as I used to play SM/CSM/Daemon in TT 40K.

night lord the novel. former axemaster whatever the hell his name was fights the main char. and axemaster is a deamon prince, main char pretty horifid by it (being an other night lord former lord himself)

do not have prove of possesed but if there a deamon prince nightlord lord there must be some. probly less them some others

ps nightlords and alpha and maybe even iron warriors are my fav chaos ones. the 4 big ones are too unrepentat slaves or fools those tree see chaos as a means too and end too the war (mostly)

Becoming a daemon prince does not necessarily mean submitting to one of the four chaos gods. There are both lesser beings (somewhere between greater daemon and godhood) such as those noted in Dark Heresy. There is also the path of learning about chaos and using the knowledge to ascend without a patron. Tough but it leaves one independent of the gods.

Thank you for the reference: I was unaware of it. However, given the reaction of the other Night Lord in your example, I do believe what you've pointed out is an aberration; much like finding a corrupted librarian in a loyalist chapter. I'd still label the Night Lords, as a whole, as 'Renegades' and would expect their members to avoid the corrupting force of Chaos as much as possible.

For my own enjoyment, and hopefully the entertainment of my fellow forumites i've decided to make a small list of terms and how I personally would apply them.

Heretic - humans holds a different view of the Imperial Faith than those that are accepted by the Ministorium

Heretek - no need to expand on this one I would think

Traitor - someone who was once part of the Imperium but has actively turned against it

Renegade - someone who was once part of the Imperium but has abandoned its authorities

Xenophile - humans under Xenos influence or who traffics with Xenos or their artefacts

Apostate - someone who has left the Imperial Faith and denies the God Emperor

Blasphemer - humans who are specifically targeting the Imperial Faith

Rouge - someone who conducts and activity on which the Imperium has a monopoly, outside of Imperial authority

 Rouge - someone who conducts and activity on which the Imperium has a monopoly, outside of Imperial authority

And I always thought that one should be 

Rouge - someone who paints himself with a reddish colour, oftentimes affiliated with Slaanesh.

A common misconception :P Nay, it should of course be rogue and not rouge.
 

cant say how rare it is becaus the mortal nightlord lord was trap in a eldar warp trap from not long after the nighthaunter was killed. and the deamonprice one was an active nightlord lord in the intervening years.

nightlord (imho) probly not a lot of deamo princes but thats me

and the relative closeness of a deamon prince too there deamon lords is an on going debate. seeing they are deamon (too the other deamonkind) but with more free will (with most greaterdeamon don`t like much) if a follower of god nr 1 became a deamon prince he would still follow god nr1 just in his own little way (how much that is and how little that is is relative too the deamon prince in qwestion.

the rebelion (for most) started becaus they thought the emeror was taking more power too himself and didn`t trust them too lead (a grave insult too a 700 or more going general of the largest army ever seen) they see them self (if faring degree) as the true savors of humanty (at least at the start)

i`m asuming somekind of viewpoint shift has been made in the on going milenia
