The 24 × 24 Grid
A–X / 1–24, one inch, no cheating the diagonal
The board is a coordinate grid, not a pretty mat with implied squares. Border it A–X along one axis and 1–24 along the other. Print alignment and bleed still require verification, so for the home prototype you rule the grid yourself.
Substrates for the master board
| Material | Size | Notes |
|---|---|---|
| MDF or hardboard | 24 × 24 in, ⅛–¼ in | Stain it dark, grid it in pencil, seal. Best lasting master. |
| Foamcore | 24 × 24 in | Fast, warps with paint unless sealed both sides. |
| Corrugated cardboard | two layers, cross-grain | Cheap Test A board. Glue, weight overnight, grid in Sharpie. |
| Neoprene / cloth | with printed grid | Later manufacturing. Not required now. |
Each coordinate normally costs 1 movement. Diagonal is legal. A diagonal move cannot cut between two blocked coordinates—so your wall tiles must actually block the corner, not sit as a thin strip that minis squeeze through. Adjacent means any of the eight surrounding coordinates. Build walls on the coordinate, not on the line, unless you commit to line-walls for the whole set.
Twin Thrones
Flex 087: two players use the central 18 × 18. Mask the outer three-cell frame with a paper collar or simply do not populate it. Chaos starts at 1. Three Discovery markers. This is Test A. Do not build the full 24-foot-feeling cathedral for the first session.
Resonance columns
Up to 24 potential Resonance Points associate with columns A–X. You do not sculpt 24 obelisks. You sculpt three or four and place them where Seed says. Empty potential is a mark on the master grid, not a pile of unused resin.
