[Ebonwick Fortress]
Soldiers standing on the walls were thrusting the spears without even taking a proper breath.
Suddenly, they felt a breeze of wind and forgot their work as they saw a giant tornado rising from the ground as light and fragile undead skeleton bodies left the ground and got sucked into the vortex of wind, turning them into fine grinding dust.
Seeing this soldiers also started feeling the suction force of the tornado as the light bodies of the skeletons trying to climb the wall started to fly and got sucked into the vortex.
As the soldiers felt a chill down their spine and quickly started to climb down the wall from the inner side to protect themselves from the suction force of the vortex while the walls shook violently and cracks began to appear on walls which have remained intact for thousands of years without a single crack or rupture.
