Delving deep into the western face of The Crystalline Mountains, The Echo Caverns form a vast underground network where sound behaves according to magical rather than physical laws. These limestone and crystal formations create chambers where echoes preserve themselves indefinitely, some reportedly containing voices from centuries past. The caverns host the highest concentration of Echo Ghosts in Elvarien, these spectral entities replaying significant moments from the mountains’ history for those quiet enough to listen. Bards journey here to learn ancient songs otherwise lost to time, carefully transcribing melodies that repeat endlessly in specific chambers. While the upper caverns have been partially mapped and made accessible with magical lighting and established paths, the dangerous deeper sections remain largely unexplored, rumored to contain valuable crystals, minerals, and perhaps even the echoes of extinct languages and lost knowledge. The temperature throughout the caverns remains constant regardless of outside weather, creating an ideal environment for preserving both sounds and certain rare crystal formations that would destabilize in variable conditions.
