It’s the robes they are so freeing.
You often wonder why would someone join a cult dedicated to the “Old Ones” or possibly dedicated to raising the dead thereby bringing about the inevitable zombie apocalypse and dooming us all to becoming nothing more than snacks for the teaming hordes of the relentless zombie army.
It’s the robes! Good, Cthulhu! Think of the comfort! It’s like wearing a Snuggie only slightly less stupid and with more blasphemous runes stitched into it.
I want one. Where do I sign up to be a cultist?
