Overview

The archipelago is a huge cluster of islands, containing plenty of trees, stone and basic ores together with a decent amount of space for building a base or settlement. It has two secret spots containing a mithril node and an underworld section, as with all continent-level islands.

Mithril Location

The mithril node is located in a cave that can only be entered through an underwater entrance. It is easy to reach, needing only a few seconds of swimming to reach the inside, which is rather small and only contains the node. Video with location below.

Underworld

Just like the mithril node, the underworld cave is also only able to be entered through a spot located underwater. Once you are through, you will find a decently sized cave with a few ores inside, as well as another underwater entrance to the second cave, which has a nice patch of land for you to plant trees and whatever else in.
