The Overworld is the crust of the Hallowed World. In the modern day, the world consists of three main land masses: Silk Archepelago, Ash Volcano, and Splatter Island. 

The Silk Archepelago is a collection of small islands. Through the Reflekt, we learnt that the Silk Archipelago used to be one full island, which was split into the modern day archipelago due to a major catastrophe caused by the Chifäns.

The southern part of the Silk Archepelago is named The Cradle, as the only islands big enough for monsters to live is located here. Undertake Voyage and Silk Cradle are located here, as well as the enterance to The Caverns. 

Ash Volcano and Splatter Island remain unexplored by our research team. There's also much open sea yet to be charted.
