From publisher blurb: A One-Page Fantasy Adventure for Player Levels 6 to 8 Compatible with OSRIC and Most Fantasy RPG systems Beneath the ruined fortress of Skull Keep lies an ancient secret. Its forgotten halls hold the secret entrance to a vampire's lair. Marauders disturbed the beast, and now it thirsts for mortal blood! Greetings adventurers and Game Masters! I am pleased to announce release of the fourth adventure in my Old School Series, and my second One-Page Dungeon, “BENEATH SKULL KEEP"! This adventure is intended for 4 to 6 seasoned adventurers of levels 6 to 8. In this scenario, which the Game Master may flesh out on their own initiative or simply run "as is", your players will be entering the dungeon level of a ruined keep, on the request of the local sheriff, to reconnoiter the activity of a group of vicious marauders who have recently taken up residence there, eager to plunder its riches. Synopsis: The ruins of Skull Keep have been abandoned for centuries. Local legends claim dire evil and great magic can be found there. Recently, marauders went looking for these lost treasures; none were ever seen again. The local Sheriff asks you to confirm the fate of these marauders. Do you dare to delve below Skull Keep? This one-page generic scenario is written to be compatible with most fantasy role-playing games (FRPG). It should be useable with any FRPG ruleset.
