Edgar did the whole of the Solar Auxilia, there's even a bunch of unreleased stuff.

Long story short: Edgar wanted to try sculpting digitally, so as a proof of concept, he did the Solar Auxilia, which GW liked so much that they made into, well, the Solar Auxilia.

He's doing is own stuff now.
I'm not surprised he left GW, when you see the stuff he sculpts you want him as free as possible.
