The magic stones have a unique power to disturb Aether currents, and they sometimes float up to the sky when the power of Aether becomes strong.

Archon's Shadow Legionnaires on scouting missions have been known to collide with those magic stones or suddenly fall out of the sky, suffering grievous injuries.

Blood for blood! This will keep us safe while flying. Thank you for the assistance, [%username].

Ragna said that there are Floating Mystical Stones in the Plateau of Aetheric Gales that impede flying by disturbing the Aether currents, and asked you to destroy them for everyone's safety.

You encountered and destroyed these stones, and reported back to Ragna.
