Kraken Corpse Delve

From publisher blurb: Everyone says the world is dying. Today you meet a stranger who has already seen it happen. She has traveled back through time to save the world…but only if you can save her! An eldritch woman from the future begs you to save her from her sister, who wants to drag her back to her own time. To close the time portal, you must climb down through the buried corpse of a kraken. The prize? A giant diamond worth 10,000 GP…if you can pull it out of the portal! ADVENTURE TYPE: Exploration / One-Shot / Dungeon Delve / Low Level
