Each row: location name, country (autocomplete like story Secondary countries — drives the flag), and why it matters (e.g. Place of birth, Former base).
Connections
Use the Hero, Faction, and NPC blocks. In each block, + Add adds a row: This entry (you), relationship lines in the middle, and one linked name (autocomplete for that type only). Choose A (left) or B (right) for this entry on the slide; the linked side uses the other letter. Legacy rows without a letter default to A. Saving mirrors onto the linked row in this same archive when that row exists; cross-archive links are not duplicated.
