Crossing the Veil
One released achievement confirms a task involving helping Grandpa cross the Veil. Exact route details are added only when verified.
Master XII secret
A separate achievement references discovering Grandpa’s big secret under the Master XII wording. Treat it as its own secret-state check, not automatically part of the Veil milestone.
Do not conflate the two goals
Completing one Grandpa condition does not prove the other is done. Keep two checkboxes in your completion notes.
Link into secret cleanup
If the main character thread is complete but the secret goal remains, move to the secrets page rather than replaying the entire Grandpa sequence.
Core game facts are limited to the official Steam store/demo and official Steam news; achievement-specific scope is based on released platform achievement metadata.
