The Stillness, Necropolis.
While Caesar was overseeing the construction of the camp's defenses, Orion descended into the hidden necropolis beneath the castle.
Clymene stood within a summoning formation, wreathed in a tangible aura of death. As the formation activated, the agonized wails of lost souls echoed from the void. The offerings placed within the circle began to decay at an impossible rate, flesh and blood turning to dust as their life essence was siphoned into a pile of pristine white bones. As the wailing faded, skeletal warriors began to claw their way out of the sacrificial remains, their empty sockets gazing around in mindless confusion.
Hsssk!
A low hiss escaped Clymene's lips. As if bound by a sudden contract, the newly-formed skeletons shambled out of the sacrificial ritual and into the nearby graveyard, where they lay dormant, awaiting a second awakening.
