01
One destination
A Threshold is a doorway built on a valid Thread between locations. Every stable Sanctum entrance reaches the same underlying place, regardless of the universe in which it opens.
02
Different arrivals
Travelers from separate worlds may find themselves at the same doorway, observing different skies beyond. Relative time is a complex problem and should not be assumed to synchronize automatically without a specific rule.
03
Security and access
The Sanctum can admit visitors without making every room available to them. Sealed Thresholds, wards, broken correspondences, and differences in individual Signatures can affect navigation.
04
Broadcasts
Lunor's livestreams can be presented as transmissions crossing a Threshold into our world. Community members are listeners and visitors, not automatically characters with cosmic power.
