Overview La Vitalis: Immortal Loss is a conceptual, narrative-driven project blending speculative fiction, ritual aesthetics, and interactive systems. This handbook (v0.11 Beta — key: B♭) distills the setting, core mechanics, character archetypes, thematic motifs, and creative prompts to guide writers, designers, performers, and participants. Treat it as both a reference and a toolkit: modular, suggestive, and intended for iteration.
