Holiday World
The Holiday Worlds of Old are separate realms that are each linked to each other and the outside world. The seven Holiday Worlds represent Independence Day, Halloween, Christmas, Thanksgiving, Easter, St. Patrick's Day, and Valentine's Day. Each Holiday World provide whichever holiday it is...
Does any one else find this to be a cool seed for a setting, a bunch of Holiday worlds with portals in each to the others on trees in hinterlands?
You give each their own D&D twist.
