Big in Japan
Forcelia may not be the setting most westerners associate with Dungeons & Dragons, but outside of possibly Mystara due to the duo of Capcom arcade games, Forcelia is likely the most recognizable fantasy tabletop world in Japan. You may be curious why you cannot recall a Campaign Boxset or Gazetteer for this setting.
Well, for as famous as the world of Forcelia is in Japan, home to the continents of Alecrast, Crystania, and the tiny dark island of Lodoss, with dozen or so RPG books and novels, we know it in the west almost exclusively through the anime that spawned from it, Record of Lodoss War. The beginning of this world was published as a series of RPG Replays, retelling the events of their RPG Campaign in magazine articles , decades before Actual Play podcasts would become popular in the west.
