Knight Houses

Each House of Knights has a strict hierarchy and ancestral martial traditions. At the head of these structures is the Seneschal, supreme leader of the forces deployed or master of a fortified stronghold on their home world. Under his command, the Scions form the elite of the Knights' pilots, divided into different categories: Aspirant Scions, novices aspiring to glory; Martial Scions, seasoned veterans who form the core of the House's forces; and Lord Scions, holders of titles such as Baron or Margrave, who have proved their worth in battle and strategy. This rigorous organisation ensures formidable effectiveness on the battlefield.

Among the notable Houses is the House of Taranis, originally from Mars. During the Great Crusade, their armour was predominantly dark blue. However, during the Horus Heresy, the survivors repainted their Knights red, as a tribute to the loyalist Florge-Worlds that supported them. Their emblem, initially composed of the Cog of Mars, was enriched with a traversing sword after the Heresy, symbolising their resilience and honour. The House of Taranis illustrates the fusion of martial traditions and technological devotion typical of the Houses of Knights, making a significant contribution to the conflicts of the Heresy of Horus.
