For the past nights you are plagued by the same recurrent dream: an ancient temple in the middle of a stormy sea that promises a great secret in your quest of protecting File Island. Although you don't know what to think of it, your team members are convinced that there is no coincidence, and suggest you a trip in search of the mythical island.
This might all be a hoax, but you trust the power of your Digimon team, and are sure that nothing can stop you. And indeed, you made your way out into the open sea in no time. The ships were not in their top shape, but nonetheless you are all confident that the journey should take no more than a day.
The sun is shining bright and the waters are calm, but the island is nowhere in sight. You decide to search for it until tomorrow morning, as the forecast announced no storms.
In the middle of the night, the waves suddenly grew so high that the whole ship is rocking threateningly from side to side. Waking up, you realize that the ship is surrounded by some kind of vile creatures that are desperately trying to tip you over!
In the next instant, a team member instantly shoots a bolt of energy straight ahead: you follow the light and see that a huge creature was trying to walk on water towards you! Shouting at it, the Digimon replies:
"Remember me? I, the great Ex-Tyranomon, am finally a puppet-master and will destroy you with these enslaved Raremons. This time I shall succeed!"
