This area has no class on the game's biome grid (caves and sub-areas live in the spawner tables only), so the map has no border to focus; the dots are its pins.

About Fabricator Caverns
Fabricator Caverns reaches 637 to 1119 m deep by the heights of its 27,620 baked slots. The resource with the highest expected count here is Silver (about 60 per game), the creature is Spinefish (about 833).
A pin belongs to the area of the nearest baked slot within 30 m (3-D, so a cave counts for its own area); a pin with no slot nearby takes the biome-map class above it (2-D). Placement of pins, depth and the spawn ranking are read from the game files; the spawn numbers are a model and have not been verified in a running game.
Depth is metres below sea level, read from slot heights. Coordinates are the game's world metres, x east and z north.
