A God is a being who’s very existence changes the nature of the universe.
A demon is a being deliberately imagined and created by the Gods that everyone agrees brings nothing good to the table.
A plot in which our heros travel across the Dreamscape fighting monsters and exploring the subconscious is cliche.
This plot has all three.
A small group of men stares intensely at something. Coming nearer, you see puppies, obviously still young, as they are small and only learn to walk. Cute as they are, the men look serious and exchange a comment here and there, making their mother nervous. But one man keeps her somewhat calm, while looking with others on the little ones.
The puppies are a completely new dog breed. The breeder hopes for better characteristics, the other men are mostly hunters and other dog-fanciers, that were called or came from own interest. If all looks well, they will have business. But now, they are just watching.
