Towards the end of “In the Shadow of the Relic,” you’ll interact with Sebastian outside of the dungeon, and you’ll be given a prompt during your conversation where you can choose:

No one should know that curse.
Everyone should know that curse.
Choose the second option, “Everyone should know that curse.”
