Exotic Beasts

Exotic Beasts came from the Spatial Gateways and attacked Mercury.

After the Mercury Alliance was formed they entered the Spatial Gateways and discovered a new world on the other side, where Exotic Beasts didn't leave a corpse when they were killed but a Beast Card.

However if you killed an Exotic Beasts on Mercury they wouldn't leave Beast Cards but their corpse.
