How to Unlock the Sealed Sanctum in Palworld

To unlock the Sealed Sanctum in Palworld 1.0, players must first reach the World Tree endgame area.

From there, they need to defeat three guardians across the map: Silvance, Dandilord, and the boss at the Forbidden Laboratory.

Each guardian drops a required key item that breaks the seal and opens the final path forward.

Because the Sealed Sanctum is one of the last main-story gates, this boss checklist is essential for endgame progression.
