Released January 2026, 'To Our Yesterday' is the sixth main-story arc and the biggest Rafayel content drop since launch. Xavier and Rafayel are co-POV characters across four chapters. Rafayel's chapters are 3 ('Drifter's Reply') and 4 ('Divergence Stirs'). Confirmed sub-chapter titles for the Rafayel side: Edge of Civilization (3-6), Whalefall City (3-7), Seaside Dirge (3-8), Interwoven Drifts (3-9), Whale Ash and Lighthouse (4-4), Where Ripples Begin (4-12). Most significantly, Whalefall City — previously only referenced as mythological lore (the final resting place of every Lemurian soul and the destination from Sea of Golden Sand) — becomes an on-screen main story location. Full story beats not available at time of writing.
