This is the classic AD&D module, I6: Ravenloft via the AS&SH ruleset. The group will be starting the game being dropped off by Strahd’s carriage at the gates of the castle, and exploring the castle at his “guests”. Experience with the module is welcomed as well, as the referee may throw in some twists. The game may very well go past the 4 hour mark, depending on how long Strahd decides to toy with them…
