I have no diea of the newcron stuff.
No idea why he fought cypher but it was mentioned he fought something that was described as a golden metal figure etc.
Man I am getting a bit grumpy right now, I miss the days when gw didn't SPELL EVERYTHING OUT.
It left room for interpretation ad kept the fluff vague enough so that not everbody is loosing hands (Helbrecht,Marneus).
Man, good old times.
I miss my build it yourself kit with IG, SM and the many many chaos lists in 4e.
Back to topic:
Most older stuff wasn't that bad I think, being a dick has a long tradition in 40k.
I still like the poker round analogy of tzeentch, big E, the deciever and Ceogorach.
