Event 11, where Kite reads the Book of Twilight, ends in story area 15, Hidden Forbidden Holy Ground. The survey of the opening arc listed its map as a blocker: area 15 is not a generated field but a hand-built one, EVENTAREA02 over the scene file se1_2, and the port built a field from its words instead. An agent has now ported the map, its church and the door between them. docs/engine/evarea.md has the detail.

What happens now

• Arriving. WORLD_MAN::GO(1) takes its story-map branch when the story area's EVENTAREA_INFO.model is set: eventAreaFlag, the -48000..48000 bounds, and a new EVENTAREA02. Kite arrives at DMY_marker01, at the foot of the bridge up to the church, from the Chaos Gate's words (from --mode story:11 too) or with --mode field:15. The event sound bank (5) is loaded.
• The map. ChangeBlock builds a block from its tables: static models, the lanterns' animation, background clumps, the lights of an animation, the fog, and the start place. The draw follows EVENTAREA02::Draw, layer by layer: the scrolling clouds and water, the mountains without fog, the lanterns and their reflection under the church's floor (revAnm).
• The ground. Each block's collision is its floor model's one Hit chunk, enabled as the STATICMODEL is built. On a story map ccLandHitCheck never falls back on a height map, and WORLD_MAN::GetHeight is 0.
• The door. WORLD_MAN::Enter on area 15 changes the block (ChangeBlock) and then the scene's block. The set-up after it keeps the map: WORLD_MAN::Quit spares eventmap for area 15 when the next area is a field. Kite then stands at once, at DMY_marker01_2 inside the church and at DMY_marker02 outside it: ccPlayer::ccPlayer plays the arrival only coming from a town.
• The lens flare. Six ccEffs of town_z, drawn in the church toward the holy ground's sun, over everything on effLayer, through piney-effect's sprite draw.
• The battle. The field's frame (the battle's tasks, the effects) runs over the map as over a field. EntryGimmick places nothing on a story map, so only the events bring enemies there.

How it was found

• SetActiveLayer's jump table. It is not in order: 3 is effLayer and 4 floorLayer. The first draw check put the flare and the clouds on floorLayer; the game's own draw in eemu put them at priority 20.
• The lights. ChangeBlock deletes lightList[lightNum - 1 .. 1] and never index 0, which looked like a light leaking into the church. It does not: deleting the light animation destroys its lights, and ccLight::~ccLight takes each out of the group.
• The door's ground. The doorway floor that carries the Enter bit is half the doorway (x 0..190). The bridge's walls lead Kite onto it.

Checked

tools/test_evarea_rs.py builds EVENTAREA02 with its own constructor in eemu, over se1_2 as Pieces serves it, beside the evarea_probe example:

• The set-up. The constructor, then the church, the holy ground and the church again: the models, the static object, the clumps, the lights, the hits enabled, the fog, eventStartPos, revAnm and the flares' Init and render state.
• The draw. 662 frames of EVENTAREA02::Draw in both blocks, with every piece in order with its layer and matrix, the animations' times, the flares' positions and MoveTexture's offsets. The lens flare alone is checked for 400 random camera states.
• The ground. ccLandHitCheck at 1,500 points of each block.
• The door. WORLD_MAN::Enter from game block -1, 1, 0, 1 and 0, with the ChangeScene it asks, then SetCharPosition.
• The walk. 3,000 frames of camera and player over both blocks: up the bridge into the church's door, random pads, the nave and out of its door, with Enter on the same frames. None differ.
• In the runtime. Three piney-game session tests: --mode field:15 through both doors; the gate's words from Mac Anu; and the same from --mode story:11, with the event task's passes ending in play.
• The rest. The workspace's tests, clippy, fmt, the docs check and tools/test_field_rt.py pass. Re-run in a clean worktree on top of 83: the story map, field, world, map and dungeon suites.
