本頁做什麼？What does this cover?
與 星際戰團速覽 對應，本頁整理 9 個荷魯斯叛亂時代叛變的 Space Marine 軍團。這些軍團與忠誠戰團不同──它們沒有被拆成「Chapter」，保留了完整的 Legion 規模 (10,000+ 戰士)。
The counterpart to our Space Marine Chapters page. Here we cover the 9 Legions that sided with Horus. Unlike loyalists, traitor Legions were never broken into Chapters — they retain full Legion scale (10,000+ warriors).
