Nagol is the yam-harvest land dive of southern Pentecost Island. Men climb a tower of timber and liana built on a cleared hillside and jump with two vines tied at the ankle, aiming for their shoulders to brush the tilled soil below. No nails, no rope — the whole structure is vegetal, and the ground is hoed soft and raked again before every jump.

The design system takes its structure from the tower, not from the jump. Stacked horizontals at shortening intervals, diagonal bracing, joints that read as bound rather than welded, and a page ground the colour of freshly turned volcanic earth. Every edge is cut or split; nothing here is milled smooth.
