Every year, on the very same day, the city of Cape Coral has been besieged by a giant Kraken, killing dozens of people and destroying huge chunks of the town. That day this year is approaching quickly -- in fact, the town has only two days left to prepare. Princess Lua, the daughter of the former king of Cape Coral, has reached out to the party to beg their aid in protecting the town. The Kraken is far too formidable a foe to try to attack alone, so instead the party must convince as many factions of townsfolk as they can to aid them in the fight, set traps, and fortify or evacuate the town. After their two days are up, the Kraken attacks, and the party, supported by whoever they managed to convince, must face it in battle. Along the way, though, the players have a chance to figure out why the Kraken attacks in the first place -- and, if they are quick and clever enough, they can stop the attacks for good.
