Dragons would make a great portfolio imo. You can have sky dragons, sea dragons, land dragons, big dragons, small dragons, dragons with opposable thumbs, giant dragons that you kill to make enormous castles from their skeletons, tiny dragons you keep in a cage like a hive of bees... lots of stuff you can do with dragons.

The trick to working with portfolios in Divinus is usually just figuring out how to solve problems with only a handful of specialties. In this case dragons.
