Imagine: Dragons (Radioactive)
So it's been a few years since I've played Warmachine (the Privateer Press game, not the Marvel guy), but there's a part of their Iron Kingdoms lore that always seemed really cool. They've got dragons that fit the usual description: big, winged, fire-breathing reptiles that each come with a godlike superiority complex. But if you manage to kill a dragon in the IK world, there is a large crystal at its heart that contains the <i>actual dragon</i>. The athanc crystal holds their true identity, and any biomass they accumulate for a body is just a fun means for hauling that big rock around. "Aha!" you may think, "so to kill the dragon completely you have to break the magic rock! That's a neat complication to your usual dragon fight." And then you'd find some way to break the athanc and learn a very important lesson. Breaking the crystal doesn't destroy the one dragon. It just makes MORE dragons. This lesson was first painful...
