The Checkpoint
The District 1-side surface entry to District 5: a wide stairwell mouth with an NPC attendant at a desk logging traffic for Beacon records. The only monitored entry to the district, which means it is the only entry point where a player's visit to D5 has a guaranteed Beacon log attached to it.
A pinboard on the wall behind the attendant accumulates posted notices of varying credibility and age: active toll route rates, known hazard zone markers, anonymous player-posted warnings. Every other entry into District 5, through stairwells in Districts 2 and 6 or maintenance hatches in District 3, is unmarked and unlogged. Players who use the Checkpoint are making a deliberate choice about what they are willing to have on record.
