I hope someone else here can help me out. Some time in the not too distant past I found a document somewhere in the wilds of the 'net that had been put together giving with current 40k edition write ups for ten or so of the primarchs and other important figures for use in horus heresy refight scenarios. (The characters were grouped together by what major battle they were at) I thought it was a particularly good adaptation which struck a good medium between game balance and the power of these heroes. I thought I downloaded the .pdf, but I can't find it on my computer, nor can I remember what website I got it from, nor find it again after a couple hours of web searches. Does this seem familiar to anyone? I'm really hoping to find it again.
