The Crag Field is a rocky biome dominated by large geological formations.
The Crag Field is situated between the Grand Reef, the Crash Zone, Kelp Forest, and shares its border with one of the Grassy Plateaus and the Crater Edge. It is situated south of the Aurora's engines. It features large rock spikes and rippling rock hills, bearing resemblance to the older Grand Reef, with all of which being formed on top a massive crag dropping down into the aforementioned biome.
The Crag Field is a resource-rich biome with some low-level predators. Groups of Bonesharks are frequent in the area, along with the occasional Mesmer passing by. Tiger Plants can also be found in this biome, camouflaged and mostly hidden in the grasses within the rock structures. The biome also features a grand abundance of minerals and other resources.
A few pods of Reefback Leviathans can be located drifting in the water above the Crag Field.
Lifepod 7 is found within the Crag Field.
