Hârn

Hârn is a campaign setting for fantasy role-playing games, designed by N. Robin Crossby and originally published by Columbia Games in 1983. In 2003, Crossby claimed that the contract between him and CGI had ended. An acrimonious disagreement ensued.

In the meantime, Crossby founded Kelestia Productions (KP), an electronic publishing e-company. KP and CGI now independently produce printed and online materials for use with Hârn-based role-playing campaigns and fiction.

The role-playing game HârnMaster was developed specifically for use with Hârn. It enables players, gamemasters, and writers to develop character descriptions that exploit the deep level of detail found in Hârn.
