Just because you see don't them, doesn't mean they aren't there.

Cryptids. Monsters. Boogeymen. Those things they write legends about, that your uncle and his six drunk friends insist they saw that one time, despite giving entirely conflicting descriptions of the event.

Turns out, yeah - they're out there, and more terrifying than that, they're employed. In fact, they're a pretty integral part of the work force! Some of them can operate in plain sight, with powers of shapeshifting or illusion to mask their true appearances, while others simply prefer to stay in the shadows, working from behind the scenes. That genuinely helpful phone line operator who helped you sort out that insurance claim? That was actually a sasquatch, and she's very happy to have been of service.

Pick a cryptid, or any monster from legend or fantasy that would not rightly fit into our modern society, and find a place for it to contribute and earn its keep. Consider what kind of challenges it might face and how it solves them - but beyond that, think of them as a person. A character. What are their interests, and what keeps them going through a long day of drudgery?
