Just finished having a chat with Andy Chambers, where I picked his brain a little about some background-concepts for my own Dark Eldar force. He seemed quite interested in my idea and said it was definitely a legit piece of fluff. In his own words:
"That doesn't exclude your background story of course. Hameonculi are weird fish and have plenty of renegades doing their own thing."
Look out for a video where I explain what I discussed with him in-depth and lay out my storyline for you all. Coming soon!
