Ginaz
the Swordmaster world
Ginaz was an ocean world of scattered archipelagos and the ancestral home of House Ginaz. Its fierce warrior culture, ruled by the Council of Veterans, produced the legendary Swordmasters of the Imperium.
Ginaz was a water-covered world of scattered sandy archipelagos, made famous throughout the Imperium for its Swordmasters. It was the ancestral home of House Ginaz, a warrior people ruled by a Council of Veterans, and the seat of the Ginaz School whose graduates carried the planet's name into the service of the Great Houses, including House Atreides. Frank Herbert names House Ginaz and the Ginaz School, but the planet itself and most of its history come from the Legends of Dune books by Brian Herbert and Kevin J. Anderson. (Dune (appendix); Dune Messiah; Expanded books: Dune: The Machine Crusade)
A world of islands#
Ginaz was similar in size and atmosphere to Old Earth, though its surface was covered in far more water, more than ninety percent of the whole. The land that remained consisted of scattered sandy archipelagos bearing minimal vegetation. It was the ancestral home of House Ginaz, and it became renowned across the Imperium for the Swordmasters it trained. The Great Houses sent their warriors to the Ginaz School, a connection remembered in the service of the Atreides line: Duncan Idaho is a Swordmaster of the Ginaz. (Dune; Dune Messiah; Expanded books: Dune: The Machine Crusade)
History#
The world had long been home to a small but ferocious culture of warrior humans. These people played an important part in the Butlerian Jihad, where they fought as mercenaries in close combat against the thinking machines. In 164 BG an asteroid fell upon the planet and raised a massive tsunami that engulfed most of the colonized islands, but after seven decades the civilization was rebuilt. Over the millennia these people evolved into the renowned Swordmasters. (Expanded books: Dune: The Machine Crusade; Dune: The Battle of Corrin)
Frank Herbert's own note on Ginaz is short. The glossary of Dune calls House Ginaz one-time allies of Duke Leto Atreides, defeated in the War of Assassins with Grumman, the world of House Moritani. (Dune (appendix))
Culture#
The people of Ginaz were a warrior culture, ruled by the Council of Veterans. Each warrior was required to father at least three children, one for himself, one for his mate, and one for those who could not have children of their own. Children seldom knew their parents, being raised instead in crèches, communal training groups devoted solely to the making of fighters. By custom each fallen warrior was held to be reincarnated in the body of a new one. When warriors graduated, they took part in a ceremony in which each drew a coral disk inscribed with a name, their hand guided, it was believed, by the spirit that inhabited them. The record of each fallen Swordmaster was preserved in a database buried in vaults. (Expanded books: Dune: The Machine Crusade; Dune: The Battle of Corrin)
