Concept: a magic-heavy D&D campaign where the party is charged with investigating the gradual proliferation and expansion of dead magic zones, with the mid-season twist that the “dead magic zones” are discovered actually to be bubbles of a setting with a different magic system.
I like the poster’s implication that the producers of Sesame Street did not put a counting vampiric count on a children’s educational series to teach kids how to count; this was just an incidental side effect of their fidelity to obscure vampire folklore.
