Last Thursday night on the drinking stream, there was a bit of spirited ([URL="https://www.youtube.com/watch?v=CndVtLvCMEI"]SEE WHAT I DID THERE!?[/URL]) debate on which Chaos Gods corresponded with which Harry Potter Houses (I know... you had to be there, I guess).
I know very little about Harry Potter, but I do know my 40k influences... but every last man jack of the players were absolutely smashed by the stage of this 'debate', so I let it lie. But, chances are people aren't absolutely smashed right now, (plus I just remembered about it this morning) so here we are.
The Big Four were originally based in large part on the concept of the [URL="https://en.wikipedia.org/wiki/Four_temperaments"]four temperaments[/URL], which itself has its roots in [URL="https://en.wikipedia.org/wiki/Humorism"]humourism[/URL]. The corresponding humour for each Chaos God is this; Nurgle - phlegmatic, Khorne - choleric, Slaanesh - sanguine, Tzeentch - melancholic.
Why the Chaos Gods are based on any of these things at all goes back to one of 40k's original influences: the author [URL="https://en.wikipedia.org/wiki/Michael_Moorcock"]Michael Moorcock[/URL]. The Four Powers have grown and developed a lot since their inception, but that's (very basically) the root of them.
So, how do the Chaos Gods correspond with Harry Potter school houses? I still have no idea. To me, English schoolkids are more like football hooligans, so a better question would be "Which Harry Potter House corresponds with which Ork Clan?"
