His worries were entirely unnecessary.
Dressed as a common Elven Mage, Mourinho, before anyone could react, suddenly crushed a Moonstone at his feet.
Amidst a sharp ripping sound, the snow-white wings on his back unfurled with a "whoosh". As his cloak shredded to pieces, fluttering in the air like butterflies, a pale blue elemental halo spanning around seven to eight hundred square feet was thrown from his hands, perfectly enveloping the Dragon people and the Blood Elf Mages under the moonlight.
"Sky Banning Song!" Liu was shocked as he watched the black figures plummet like dumplings, his eyes and nose nearly crooked in astonishment.
He really hadn't expected it! Liu almost forgot that Mourinho was a Smey!
The blue sky is the hereditary territory of the Smey Clan; no creature relying on air to fly has the right to cross their airspace!
