The Sundered Deep adventure

vast subterranean realm beneath the eastern half of the Etyma supercontinent — collapsed lava tubes, bioluminescent crystal caverns, and deep warrens that predate the Erasure. The Sundered Deep is home to a fragile alliance of underground races: the phasing Vorpal Bunny Folk who patrol the hunting tunnels, the echolocating Gloam Hare who map the passageways, the stone-quilled Cobblehog Folk who excavate new routes, the volcanic Obsidian Newt Folk who forge near subterranean lava flows, the bioluminescent Wormroot Folk who farm fungal gardens and heal the sick, and the Tunnel Vole Folk whose trade network connects every community. Moonrise Warren in the Northern Frontier is the closest surface entry point, connected to the Deep by ancient tunnels.
