An Old Friend would like to have your party for dinner…
Zargon (Solitary, Large, Planar)
Tentacles (d10 damage) 24 HP (1 armor)
Near
Special Qualities: Regenerates, Horn must be destroyed to kill
Although Zargon is ancient, it is no god. It is a cunning creature that discovered its “godhood” makes it easier to get victims. Zargon was worshipped by primitive peoples in early times, but retreated underground when the primitives were wiped out by the ancestors of the Cynidiceans. Zargon remained in a strange hibernation for many years. By chance, the Cynidiceans built a palace on the spot where Zargon’s original shrine stood, and the later digging of the Cynidicean slaves awakened the creature. Zargon can regenerate its body as long as its great horn is not destroyed. Regeneration from the bare horn may take a number of years, but otherwise Zargon is likely to be at full strength whenever the party encounters it. Zargon’s horn can only be destroyed by being cast into a volcanic fire. Zargon will not regenerate during an encounter (it regrows too slowly for that).
