I saw this picture today (great piece imo), which sparked a thought; Can/would Dark Eldar align with Chaos?
Dark Eldar: Mark of Nurgle by Beckjann
By my understanding, they hate Chaos just as much as any other Imperial fella, right? What's the usual procedure(?) when it comes to aligning with Chaos?
Best Answer
In my opinion - no.
Their cruelty is a way to AVOID chaos - since they have no spirit stones, that would protect their soul they instead sacrifice souls of others. It is a bit paradoxical: they do chaos work while despising it at the same time; they do what Slaanesh cultist do but at the same time they despise them and hate the She Who Thirsts for destroying their ancient empire. If you'd prefer to use Warhammer Fantasy RP alignment system, they are EVIL contrary to CHAOTIC cultists.

It means that mere presence of chaos weakens the Dark Eldars.
