+## Silence Topic
+
+What the travelers going deeper report when they come back — if they come back. Travessia is the last provisioning stop before the corridor enters the stretch toward Abzu and the unsettled systems beyond. Some of the traffic that passes through outbound does not return. The community does not track the difference formally. The provisioning logs record departures but not the inverse; there is no register of who came back and who did not. The community's practice of not asking is not indifference. It is the learned behavior of people who understand that the deep corridor beyond their position holds things that are not their business, and that knowing too much about a traveler's purpose makes the next traveler's arrival more complicated.

+## Narrative Hook
+
+The last provisioning stop before the deep corridor — where travelers going further are provisioned without questions and the community has learned not to count who comes back.
