IC - AD&D One Shots Keep On The Borderlands
AD&D 1st Edition Rules
Keep On The Borderlands scenario
Characters can try going solo and see how fast they can get killed :) or;
Characters (usually with high CHA) advertise their next adventure/mission and put together their party from characters available at the Tavern.
16+ characters/adventurers can register as available at the Tavern in the Keep.
So from a pool of players, smaller parties can do short missions and then change composition of their party for the next mission.
