The Heartlands

Overview

The Heartlands are the central mainland of Thylea, described as the cradle of its civilization. The region stretches from Estoria in the north to Mytros in the south. The Oldwoods lie to the east and the Mithral Mountains rise to the west.

The heroes travel through this region during the campaign; their first stated destination is the Temple of the Oracle.

Player Reference

A single-page Foundry VTT player handout was prepared for this region. It indexes map locations with two- or three-letter acronyms followed by a period (for example, EmP. Empusa Grove) to support quick table reference. The acronyms are navigation aids, not canon names.

Relations in the Vault

• Estoria and Mytros define the north–south span of the region.
