The artifact has been sealed for centuries and can only be activated by those who possess the right mindset and courage.
The students are determined to bring this artifact back to their own world, but they soon realize that their actions have consequences. They begin to experience strange phenomena, including visions of the past and encounters with otherworldly beings.
As they delve deeper into the portal's secrets, they uncover a dark history of the Dutch Golden Age and the people who lived during it. The students learn about the evil forces that threatened the world and how they were ultimately defeated.
