Jorune is a somewhat obscure RPG game setting, but many gamers will recognize the iconic Miles Teves art.
The background is similar to Tekumel, in that humans settle a world in the far future. But contact is broken and technology is lost, leaving humans to fend for themselves as just one of many intelligent inhabitants of an alien world.

Maustin Caji has the distinction of being written for the ultra-rare 1st edition of Jorune [see my reference site]. Ultimately, it is a comfortable dungeon adventure, Jorune-style. The party discovers a man who’d been held prisoner – unaged – for 20 years, and can lead the group to the lair of the rebellious Maustin Caji.








Nostalgia has no concern for timeliness. Throughout the subsequent years (decades really) since I first discovered “The Sky Realms of Jorune” it has embedded itself within my imagination. The sheer narrative pleasure of a game I only played once; a waxing summer’s afternoon in the suburbs of LA, has stayed with me. I recently found a few supplements & a very fine 2ed box set. I am in awe of how immeasurably remote in time, gloriously lacking in any relevance for our day, atemporally alien to our hopes and uncertainties. You have a really wonderful page here. There are assuredly monsters in this world that only Reason’s awakening will dispel but until that Age returns I will be off, wayward side, in Jorune.
I agree. I’ve never played Jorune. But I will!.
