Grids made the original city.
Human-sized networks flow off the main grid. Laneways.

Since he last spoke via proxy, the Master Codemaker has been silent. Today he began tagging sites in the city.
Sites that have history.
Sites that are part of the grid but off the grid.
Sites that have been claimed.
Sites that remain free for inscription.
Places you would not normally go.
Sites of the original network. Dead ends. Blind corners. Mixed-use zones. Self-organising communities.
Filling in the squares of the grid with codes. Labyrinths.

There may be up to 64 IDEOTAGs to find in these zones.

But the Master Codemaker was interrupted. Some sites may remain untagged…
For now, south of home base is where to start.
