Episode Deaths


  • The title of this episode mostly refers to Floki discovering the cave.
  • Though the series ignores most of the facts on the settlement of Iceland, it was reported by the earlier settlers than Christian monks from Ireland, the Papar, had lived on the island in small numbers. This has been proven by archaeologists and is meant to be the story behind the relics found by Floki.
