Investigation mechanic
Are Grave Seasons Killers Random?
Grave Seasons does not procedurally invent a murderer. A playthrough selects from a pool of authored supernatural-killer campaigns, each with its own reasoning, kill style, and targets.
How the mechanic works
The selected culprit can vary, but the narrative is written rather than assembled from random clue fragments. Guides must therefore identify the relevant campaign and avoid presenting one universal suspect answer.
What this changes for guide design
Walkthroughs must separate universal systems from campaign-specific answers, record the relevant season and resident state, and keep culprit or victim information behind explicit spoiler controls.
Verification rule
The page answers the confirmed mechanic now. Exact quest steps, item requirements, dates, failure windows, and outcomes will only be added from official material or repeatable retail-build evidence.
