WISH TO BE
Set in the lands of Aristotle, a land of mystical beings. Each person is born with their own crystal. The crystal determines which mystical animal you have as powers, forms, etc.
There are many crystals like blue, red, yellow, pink, brown, black, white, and so on. How the hierarchy with the crystals work depends on the mystic animal and crystal itself.
Dull, dark colored-crystals are the lowest-ranking; the least powerful. Shiny, bright colored-crystals are the highest-ranking; the most powerful.
The mystic creatures from a shiny, bright-colored crystal can range from a phoenix, unicorn, dragon, griffin, centaur, siren/mermaid, etc.
The mystical creatures from a dull, dark-colored crystal can range from a normal horse, rabbit, fox, wolf, or any common animal that's commonly seen and isn't considered mystic.
There can also be paleo-mystic creatures. An example is extinct animals like dinosaurs, though they're rare, as they aren't seen as much, in this world, at least.
