As an example, when I went to college I turned my back on the game itself and sold the vast majority of my models. However, I never even considered selling my novels, White Dwarfs or codices, indeed I continued to buy more. Unsurprisingly it was the fluff that eventually got me back into the game.
So, presented below is some my fluff for my Dark Angels.
It was also an excuse to mess around with photoshop...
I'll let the fluff largely talk for itself, but below is some of my thought process.
I wanted to link my DA in with my Praetorian Guard which, given that Praetoria is in Segmentum Tempestus, placed them directly in the path of Hive Fleet Leviathan. However, I also wanted my Dark Angels to keep to their main purpose, hunting the shadowy forces of Chaos. So I followed the old GW trick, and used a confused (Inquisition) outsider to describe my army as a sinister and suspicious force. The '1st Capture Force' is nowhere near the Eye of Terror or the Maelstrom (where you might assume the DA to be) and the Inquisition wants to work out why.
So who are they hunting? Are they going to undermine efforts against the Hive Fleet? Does there presence signal a previously unknown Chaos presences in Segmentum Tempestus?
Well, don't you just love a bit of GW style intrique!
It's also convenient because my main enemies at home play Chaos and Tyranids, giving me a fluffy excuse to fight both of them!
I would love to hear anybodies comments on what I have come up with. Some of this is far from cannon (the 'Capture Groups' are entirely my own invention), so I would love to know if people think it does 'fit' within the wider 40k story.
IMPORTANT DISCLAIMER: I used a lot of images found on the Internet to make this picture. I would like to stress that all are used in good faith, and should any of the owners object, they will be taken down immediately. Please contact me by commenting on this post. I hope to improve the background of the 40K universe, I'm not trying to offend any other hobbyist out there. Many thanks.
