Knights of the Old Republic remains one of the richest Legends settings for exploring Jedi and Sith institutions, war, memory, identity, and political change. Revan sits at the center of that world because the character moves through competing roles that are normally treated as opposites: Jedi, conqueror, Sith, prisoner, reconstructed identity, and later historical symbol.
The IDS Revan and KOTOR cluster keeps that biography inside its social setting. The Old Republic timeline provides the broad historical frame. Ancient Sith and Sith tradition pages explain the inherited ideas Revan encounters. Darth Traya and Naga Sadow connect KOTOR-era questions to other Legends debates about the Force, institutions, power, and historical memory.
The nightlife archive also matters here. Javyar's Cantina, the Upper City Cantina, and Jekk'Jekk Tarr make the Old Republic feel inhabited by ordinary workers, migrants, criminals, travelers, and species communities rather than only Jedi and Sith. That is why KOTOR is especially useful for IDS: its political and philosophical conflicts happen inside cities, occupations, economies, and everyday social spaces.
