The Pearl of Madness is a companion adventure made to go along with the events unfolding prior to the core adventure founding Folio #14 (WS1 ). It contains the information needed to run a side adventure that will help characters gain a degree of experience before setting out into the interior of the Isle of Jade. Thunder booms on the north of the isle and a dark rain falls on the inland swamps prompting the village chief to deny the characters canoes for their journey for another day. This respite offers the characters a chance to participate in a village tradition, the pearl dive. With whispers of great wealth at the bottom of a secluded cove, the players prepare for a dive that will provide more than the mundane. When the Isle of Jade begins to rumble, the islanders cancel the player's expedition to the inland. However, it is still a beautiful day for a pearl dive. Can the players find fortune in the tranquil waters of a hidden cove, or does something more sinister lurk there? This adventure is formatted to both 1E & 5E gaming rules.
