"Stop storing fingerprints. Destroy the compass." Harry drew his wand.
"I can't destroy it." Vivi lifted the compass before her eyes. "The compass is made of basalt, and Cassandra's runes are carved inside it. Those runes are bound to my magic. Destroying the compass would be the same as severing my Magic Circuit."
The dark-red human outline above the Stone Stele swayed. "See? Every step you took was inside my plan.
