I was really interested in the Khorne Daemonkin codex when it came out. It fixed a few things, added a few useful units for daemon players, & made me consider branching out a bit. As I evaluated my mini inventory it occurred to me that I have a lot more Tzeentch units then any other Chaos faction, so I decided then to start building toward a Tzeentch Daemonkin codex.
These are two more additions to that goal:
My Daemons have all been painted with a color scheme in mind. All Slaanesh are grey & pink, Khorne is red, Nurgle is green, & Tzeentch is blue. That's why all my "pink" horrors share a similar blue skintone. It fits thematically, since all pink horrors are actually two blue horrors, but honestly, I just like the look a lot better.
A few years back, in December, I remember reading a message board where folks attempted to judge the worst-looking miniature of the year. There had been a few contenders, but this miniature was consistently rated in the top 5.
Nurgle later today.
