Mountain Creatures

This adventure re-skins many Old-School Essentials monsters (referenced in italics). Their full stat blocks are not repeated to save space. Some creatures are unique and repeat regularly. These are described here for reference.

Cave Fish

A wide variety of alien-looking creatures sustained in the God Carp’s waters. A random fish is (roll d12): (1–4) mostly harmless, (5–7) as giant bass, (8-9) as piranha, (10) as giant sturgeon, (11) as giant catfish, (12) actually a waterwight (page 11).

Holy Animals

Sacred animals with faint aureate nimbuses, protected by the mercurial God Fish. As mundane animals with the following abilities:

• Magic resistant: Spells fizzle 50% of the time.
• Protected: If injured, the mountain immediately responds with a tremor or angry wind. Roll 1d4+1 on the challenge table.

Radiation Ghosts and Terrors

Echoes of past civilizations trapped in the God Fish’s mythic gravity. As shadows, but less immediately hostile.
