The Sith are best understood as a changing tradition rather than a single institution that remained identical across every era. Ancient Sith states, secret lineages, the Rule of Two, cultic survival, and later restoration projects organize power differently even when they claim continuity with earlier Sith names and teachings.
This cluster connects four levels of the archive. Lore files explain historical change. Religion and culture pages examine doctrine, ritual, cosmology, memory, and apprenticeship. Organization pages track institutional form. Character files show how individuals inherit, revise, exploit, or rebel against those structures. Together they explain why Sith history is as much about succession and legitimacy as it is about raw power.
The Rule of Two is a particularly important turning point because Darth Bane reorganized Sith continuity around a hidden master-apprentice lineage. Palpatine and Vader represent the political culmination of that strategy in canon, while Legends figures such as Revan, Traya, Talon, and Naga Sadow belong to different historical and institutional settings that should not be flattened into the same system.
