Port Krillmere on Krillmere Island is known for the hunting of whales. Most of the whaling industry is in the hands of the Triwhael Company, which established a research facility on the island where five mages are working on secret innovations to increase company profits. Lately, however, contact with the research facility has been lost, and one of the mages who visited the port has disappeared as well. The characters have been sent to the island to investigate.
During their time on the island, the characters may explore a cave system to find the missing mage, visit the ruins of a rich mansion infested by critters, and ultimately uncover the fate of the mages at the research facility, which may lead them into a dark and dangerous place. Optionally, they may go on an underwater salvage mission, and find out what is causing the increase of ships running into rocks near the island.
Red Flag Flying is a short campaign designed for Dungeons & Dragons fifth edition, for a party of four or five characters. The characters start at 1st level, and may end the adventure at 3rd level. It is suited to introduce new players to the game.
