Decades ago, a human named Mulmehr discovered a
particularly old series of tunnels through the mountains
and claimed them for himself. Mulmehr, a scion of the
Shahram noble family in Tyr, spent years and much of
his resources modifying the tunnels to use them in a
psionic ritual. He completed his preparations, attempted
the ritual, and apparently failed. Many of the tunnels
collapsed, and Mulmehr was never seen in Tyr again.
Whatever the nature of the ritual, the tunnels have
since gained a reputation as an evil place that drains
all sound from visitors – as well as their willpower and
volition. No one can say what lies at the heart of the
Echoless Caverns, where Mulmehr scribed the ritual circle,
because no one has reached that area and returned to
tell the story.
