I guess the rumors of Ravenloft’s return could be partially true. D&D’s current creative team just brought back Spelljammer which I bought several weeks ago and then there’s Eberron in 2019. Wait, it’s possible since the module which started it all hit stores 40 years ago. The printed adventure instituted a couple changes in how D&D was played too. I think it was the first to have an isometric map of the “dungeon” areas and the villain, the immortal vampire Count Strahd von Zarovich, was someone your players became more acquainted with. Before him, vampires might have had names (Drelzna, Kas, Ctenmiir and Belgos) but they were just another monster you kill and loot.
As for Kermit…he’s played this role before:
