I posted teasers of this guy on the 30k forum, but here he is, the completed Imperial Knight seconded to the Legio Astraman (Morning Stars) supporting the Sons of Horus. I haven't found good transfers for Legio Astraman, but when I do I will eventually add their symbol somewhere. As far as the original knightly house, that is yet to be determined. The fact that knights can be oath sworn to Space Marine Legions, or seconded to Titan Legions is simply brilliant. GW put all the hooks necessary for people to get as creative as possible with these units.
I loved every minute building and painting this model, and have two more on the way. I couldn't resist the chance to do some more carapace designs. I think white chevrons with black outlines would look good on one of the knights. The other may get white checkers, or have the center segment with the door painted white. White is such a great base color to add weathering to! With three of these guys I can use them as a primary detachment. This may even get me back into regular gaming since the force will be really easy to transport.
