Yags (Yags is Another Game System) is a generic and modular roleplaying game focussing on realistic, gritty play. The system uses a consistant and simple core mechanic and skill-based rules. It can be been used for fantasy, science fiction and modern horror gaming, but is grounded in realistic low fantasy. Combat is always deadly

Habisfern is a detailed fantasy campaign setting which was developed for Yags exclusively. The Habisfern Campaign is set in the Kingdom of Weidany, which is one small part of the continent of Euressa. It is a land of fallen kingdoms, untamed magic and wild beasts. The biggest threat of all though comes from the North - the chilling wind of the Ice, which seeks to wipe all life from this world.
