Echidna is the name of an alluring voidsent bound within the enigmatic Void Ark. The voidmages of Mhach, a city that thrived during the Fifth Astral Era, were said to have employed the fiendish entity as a strategic weapon in their endless conflicts. Scholars conjecture that as a member of voidsent nobility, Echidna likely occupies one of the higher rungs of the hierarchy.
