From publisher blurb:
Mysteriously Missing & Merrily Met is as set of optional tables for Old-School Essentials and is compatible with similar clones of the Original, B/X or BECMI editions of the classic fantasy role-playing game.
These tables answer the question: "Where have you been?", for when a player misses a session, explaining where their character has been and what they've been doing.
The set features three tables:
Last Seen in Town
Last Seen in the Wilderness
Last Seen in a Dungeon
They provide an instant retroactive story to explain why a character disappeared and was not around during the last session.
These tables aim at providing interesting events to inject more story into the campaign. Sometimes the results are simple and bear little or no consequence; sometimes a result may produce a significant change in the character’s story.
