Ways to hide the supernatural from the mundanes:

"Everyone just forgets" too contrived? "Elaborate conspiracy" straining disbelief? "Fear of witch hunts" undermined by godlike powers? Don't worry! Here are plenty of unique explanations for your horror/urban fantasy setting's masquerade.

No-one knows about the supernatural because:

• Everyone's distracted by the alien invasion that's unrelatedly happening at the same time.
• Most people assume its a huge ARG. One of those deeply illegal ARGs with a massive death toll. Several small filmmakers are in jail for it.
• Whenever someone tries to show proof of the supernatural, Elon Musk buys the social media platform that the information is put on and destroys it before anyone can see it.
• People can only do supernatural things in windowless soundproofed rooms. That's just how magic works.
• Everyone on earth forgot to charge their phones at the same time.
• It's the 2020s. Everyone's too jaded to give a shit that a dragon just ate their house
• There's not actually any mundanes left to find out about it, the last one became a supernatural being 3 months ago.
• If you reveal the supernatural then the GM will cry.
• Ix-nay on the upernatural-say! Do you want to be one to tell Azathoth The Nuclear Chaos his fast food worker disguise is shit??
• If you find out about the supernatural a werewolf will eat you. That's not his job, to be clear. He just coincidentally stumbles onto literally every person who has concrete proof of the supernatural and eats them.
• General financial problems for independent media.
• For some reason everyone keeps yelling that acknowledging the hundreds of man-eating ghouls is a violation of their freedoms?
• A very cute dog is nearby and everyone's looking at him rather then the warlocks.
• I dunno. Probably brexit.
