Subterranean Tunnel Network

Ravalox Tunnels

The Ravalox Tunnels stretch through the planet’s bedrock as dark arterial passages, their slick stone walls dimly lit by patches of bioluminescent lichen that cast weak greenish glows over uneven floors. The air hangs thick with crushed stone dust and a faint metallic tang from ancient mining operations, thickened by the constant drip of water from unseen fissures above. Narrow in places where ceiling collapses force travelers into single file, the tunnels twist unpredictably with a scale that only reveals itself when the looming silhouette of Drathro’s fortress appears ahead. Every movement echoes unpredictably—footsteps, shifting rock, the occasional grind of distant machinery—building an oppressive atmosphere where the weight of the planet presses in. This entity also encompasses the derelict 'Ravalox Underground Station Ruins', a cavernous remnant of the tunnels used during the era of the Black Light civilisation for transit between Ravalox’s subterranean and surface installations. The station ruins feature emergency lighting, condemned infrastructure, and platforms half-collapsed into the tunnel network. Both the active tunnels and ruined station share the same bioluminescent lighting, industrial decay, and navigational hazards, functioning as a continuous though fragmented underground system.
