Agency Obscura
Since the beginning of time, supernatural creatures have walked the earth. As humanity began evolving, they became strong enough to fight back against the creatures and drive them into hiding. These creatures are now considered mythical, but in actuality they live under humanity's radar, either staking out what little untouched land remains or living among the humans in magical disguises. Creatures in this latter category often form support groups in order to cope with not being able to live in their true forms. These groups are called agencies obscura.
