Nodens is a guardian. He first appeared in Kingsport Horror expansion.
Nodens - Lord of the Great Abyss
When Nodens is the Guardian, shuffle the Blessings of Nodens deck and place it facedown near the board at the start of the game.
And upon dolphins' backs was balance a vast crenelate shell wherein rode the grey and awful form of primal Nodens, Lord of the Great Abyss.
Whenever an investigator gains a Blessing card, he also draws the top card of the Blessings of Nodens deck and keeps it.
Ruler of the Nightgaunts
Instead of making a combat check against a nightgaunt, any investigator may instead have the nightgaunt drop him into an open gate of his choice by invoking Nodens' name.
Hunter of Horrors
Because Nodens is hunting the servants of the Ancient Ones for sport, their numbers are being kept somewhat under control. The Outskirts limit is increased by 1.
