The Shardfield (`shardfield`, scene `Shardfield`)

Spawns: Spawn_lanternfall_path.
Exits: back to Lanternfall; (Act 3) the old Corran road, blocked for now by a fallen shard line.
Landmarks: shelter rocks between panes, the reflecting shard that shows the square, the broken Corran road marker where the Corran shard lies.
Rough layout: an open field of standing mirror shards on the dry lakebed; a path of shelters zig-zags toward the Corran road.
