Defeating The Darkner Gerson In Deltarune
After Carol expels Kris and Susie from her house, they head back to the church to retrieve the key.

You will find another Dark World inside, filled with murals that reference the prophecy.
Here, players must seal the Dark Fountain before discovering a locked door that leads to yet another Dark World.
We encounter an old turtle-like monster who helps Susie use her magic and boosts her confidence.

Players make their way to another fountain, which leads them to a locked room with dark smoke rising from beneath it.
Susie believes there is yet another Dark World and that the Knight is still alive. A new Dark Fountain is created to open the door.
However, this resurrects a hostile Darkner version of Gerson, who intercepts and attacks you.

Players finally defeat Gerson with Ralsei’s help, who then reveals that it wasn’t the librarian himself, but one of his statues.
Susie Learns The Truth About The Prophecy In Deltarune
Ralsei reveals that she knows many things but has been keeping them hidden to avoid worrying others.

Furthermore, we can encounter the Roaring Knight, who summons a Titan fountain.
After a long battle, we finally defeat it with unexpected help from Gerson, the old turtle.
Susie runs ahead and sees a depiction of part of the prophecy that Ralsei had been trying to hide.

Before we can reach her and learn about the prophecy, she smashes it, preventing us from discovering its contents.
This heightens anticipation for the next chapter of the story and the true nature of the final prophecy in Deltarune.
