Editing Cavern Depths

{{Biome|id=cavern-depths|name=Cavern Depths|order=4|guardian=Hollow King|unlocks=Murk Sovereign (Murkwater Swamp)|relic=Cavern Relic|cave=Echoing Deep|dig=Echoing Ossuary}}
'''Cavern Depths''' is biome 4 of the ten [[Biomes]] of Primal Idle. Glowcap-lit tunnels that wind far beneath the world.

Its [[Expeditions|expedition]] patrol yields the '''Cavern Relic''', and clearing it fully opens the '''Echoing Deep''' [[Caves|cave]] and the '''Echoing Ossuary''' [[Excavation|dig site]]. Unlocked by defeating Murk Sovereign (Murkwater Swamp). Its Guardian is the '''Hollow King''', whose defeat unlocks [[Scorched Badlands]].
