Caer Mundus: The Lost Realm (2021)

Looking at some recent RPG books this week starting with this beauty, Caer Mundus: The Lost Realm (2021). It’s a system agnostic attempt to reconstruct a plausible Celtic world for RPGs (the people we call the Celts didn’t write anything down, so what we firmly know about their culture is pretty scant). It’s emphatically psychedelic, with mind-altering substances (particularly mushrooms and red honey) fueling magic, visions and bravery.

There’s a ton of tools in the book: dogs, horses, heroic rivals, a system for tracking acclaim (and social stigma), tables galore. There are templates that present Celtic versions of Bards, Druids, Rangers and Warriors that can be laid over most system’s character creation systems. There are, of course, many spirits and monsters derived from the surviving mythologies of the British Isles (selkies, dullahan, coraniaid and so on).

Perhaps the most interesting part of the book is the epic quest line, the Song of the Blaze Above. It begins with an omen of apocalypse, which spurs the three old kings to attempt to purge the ellyllon, a sort of fae culture that has co-existed with humanity. The quest sees the players recruited to unite the three kingdoms (installing new kings if necessary) in order to prepare for the coming battle with the true threat: an army of ogres (who, through their naming, are highly implied to be Romans, at least metaphorically). That battle has three potential flavors: one where humanity can triumph, one where humanity is doomed and one where the ogres are a red herring and the fae are the true threat after all. It’s neat to have all the events mapped out, and pretty clear how you can map them to a system of your choice. Along the way, characters grow from scrawny whelps to epic heroes. There’s an Afanc. What more could you possibly want?

Grim and gritty art throughout, in the vein of Warhammer Fantasy Roleplay, but slightly lighter and more realistic. You can catch glimmers of a way of life here. The cover is by Sawblade, whose art has decorated many a death metal album cover. My pal Darkwind Berserker did the logo.
