Perseides

The monsters are gone. Your forebearers killed them.

Mankind enjoyed an age in the sun and in the night. The monsters went away and the slayers followed.

Now perhaps, the darkness comes again. As the dark rises, so too must the Perseides, the heirs of Perseus, rise to meet them again.

This is a one-page, rules-light supernatural investigation RPG, that uses a deck of playing cards.
