need some help naming my warband and with writing their fluf

[Chaos Lord Rakarial 20]

Hey guys so Chaos Space Marines were my first 40k army and ever since i started playing 4 years ago ive flitted between different warbands etc.

Now ive settled down on doing a warband/legion who are corsairs similar to the red corsairs and zealous chaos worshippers ala word bearers.

Now paint scheme wise im going Ceramite white washed with Coelia Greenshade

Aside from those 2 there are a few things ive decided

The legion will number 10k marines with around 70% having the same geneseed

They will turn to chaos at the start of M34 due to feeling displeased with the way the imperium treats them which Belakor will take advantage of

If you are looking for a fanatical pirate band, may I suggest looking up the Barbary corsairs for inspiration. They seem like they would be right up your alley.

I will look them up :) cheers
