Intrepid spacers ply the vastness of the Five Galaxies in search of fortune and glory.

This is Plerion, a sci-fi hack from Cairn designed to play radiant space opera.

Inspired by classic science fiction and the RPGs that emulate it, but with a more modern twist, winking at transhumanism and cyberpunk.

Plerion is an adventure game for one referee and at least one other player. Players act as hardened spacers exploring, exploiting and commerce through the vastness of space in the far future.

Sources of inspiration:

  • Classic Traveller
  • Jack Vance's Gaen Reach
  • Mass Effect
  • Becky Chambers's Wayfarer Series
  • David Brin's Uplift Series

Plerion is licensed under CC-BY-SA 4.0 and derives from Cairn by Yochai Gal and Spacer (CC BY 4.0 by Paul Umbers).

Intrepidi spaziali solcano la vastità delle Cinque Galassie in cerca di fortuna e gloria.

Questo è Plerion , un hack fantascientifico di Cairn progettato per riprodurre space opera rutilante.

Ispirato alla fantascienza classica e ai GDR che la emulano, ma con un tocco più moderno, strizzando l'occhio al transumanesimo e al cyberpunk.

Plerion è un gioco di avventura per un arbitro e almeno un altro giocatore. I giocatori agiscono come spaziali veterani che esplorano, sfruttano e commerciano attraverso la vastità dello spazio in un lontano futuro.

Fonti di ispirazione:

  • Classic Traveller
  • Gaen Reach di Jack Vance
  • Mass Effect
  • La serie Wayfarer di Becky Chambers
  • La serie Uplift di David Brin

Plerion è rilasciato sotto licenza CC-BY-SA 4.0 e deriva da Cairn di Yochai Gal e Spacer (CC BY 4.0 di Paul Umbers).

ti segnalo che nell'edizione italiana a pagina 30, sotto Nobile, Foil è stato tradotto con Foglio invece di Fioretto



ho notato il seguente refuso : la 'protezione' delle astronavi la chiami prima PF e poi , da  pag 47 , PS.

grazie Luca, confermo PS (Protezione Scafo)

Hey could you explain an example of how one would use the species  abilities in a "mechanical" sense?

Traits are always diegetic, they have no mechanical impacts on the game

Ok cool i had to ask because if i run this with my group i know someone is going to ask if they can use there regeneration ability a lot so i was trying to figure out weather i should give something like the psychic ability as a innate ability,give advantage on certain rolls or not thanks for the quick response
