I could use some advice about making a CMS. I just got the core book, looking to get more.

My goal is to build a Nightlord Tactial marine from the long war. Ive read that in the RPG that they are found in the Tome of Blood

So my first noob question would be how can I buld the marine without falling to Khorne?

Yes Im a noob to this game system, there are SO many options to pick from thats a lot of the problem
