Khurasan Miniatures have posted a background story for their upcoming 15mm Mystri Island Stossechse dinosaur figures.
From their website:
Von Schrecklichdorf allowed himself to relax a little. “Stossechse.” Something right about that name — “assault lizards” — yet something so very wrong all the same. Scaly skin and a face like a lizard, but feathers like a bird, and a taut, wiry body like nothing he’d ever experienced before. What were they, besides damnably dangerous?
