Sky Stealer

The exact moment Ace touched the formation of the luminous library treasury. Inside Jade Pavilion's private room Dion frowns his eyebrows as he takes a grey crystal card with mysterious patterns on it. 

This was the key card of the luminous city's treasury! But this grey card was sparkling brightly a moment ago and suddenly returned to its dormant state.

Dion knows what that shine means, it means someone is messing with the treasury! 

'Did that old witch lose her mind?' Dion instantly thought of Aspen but quickly threw that notion out of his head, 'That old witch didn't have the guts to do it. But why is this key returned to its dormant state after a moment of warning? Was it a false alarm?'

Dion first thought that it should be some minor problem but frown after thinking that formation on the treasury was not so simple and if the alarm goes off that means someone is not right there.
