My son of the Warden King has been completed. I also decided to give him a companion gryph-hound. My army list may make use of him for some overwatch against anything being summoned or deep striking near my 2 big guns. So I decided to paint it in the general color of the clan throng, instead of painting the hound the colors of my stormhost.
Silver Tower box, and normally accompanies the Excelsior Warpriest. I figured since it's apparent that gryph-hounds don't only accompany the Stormcast Eternals, and are natives of Azyr, Drake could have picked one up at some point. The hammer on its collar still fits with the faction.
