“ You've probebly heard of the real Thomas Hopkins, Witchfinder-General, who hunted down and hanged suspected 'witches'. What if there was a world/realm where magic was normal, and it was the non-witches and non-wizards who were hunted down and hanged as inferior beings?”
“ The PCs encounter a strange set of artistic drawings done on the ground as they pass through a city. It has been done in chalks and no one saw who did it. Wizards might recognize the writing within the colored square as an obscure and dead language with a message stating that a prominent wizard and a retired bard have discovered how to populate Arcadia with the spirits of the dead!
Is it a local hoax, or are the PCs crossing the path of a very deranged and possibly dangerous mage?”
