User Summary:
Koros is a french roleplaying game in the "Universom" line of science-fiction games released by Siroz Productions.
Koros is a gaseous planet orbited by twelve moons, homes of the Kharène civilization, a human civilization in a state of constant war with the Thryrans (who live on other planets of the same solar system). the Kharène regime is autocratic and militaristic: the population is under constant surveillance and sexual reproduction is forbidden. The mad king Velriz Sargh IV's rules are enforced by his armies of women and his Zerig knights. The only political opposition comes from the Priest of Elenkar and their powerful psychic powers.
The rules are the standard Universom rules, with additions to cover space travel (and combat) and psychic powers.
