From the hulls of the Floating Ship fleet, the silvery-white energy barriers radiating outward from the Patronus Charms merged densely together, expanding into an even larger circular barrier that knocked the Dementors in this stretch of sky away one after another. In the darkness, that energy seemed tinged with blue, like ripples spreading across a lake, wave after wave radiating outward without pause and carrying off those mildew-like things.
And it was not merely defense. Inside the defensive ring, more and more fully formed animal Patronuses began to join the attack. Among them, a brilliantly silver Phoenix with an especially majestic appearance was particularly active; its beak, claws, and even tail were all used with nimble precision as it launched attack after attack. The area it cleared was also the widest, and the Dementors were sent flying in all directions like splashing boiling water, while the air grew warm again...
An otter that was not especially large but glowed with a moist, lively radiance was no worse than the Phoenix at driving away Dementors. Clearly, it was coordinating with that Phoenix to maximize the efficiency of their routes. At last, they converged, darted nimbly through the air in a circle, and began heading downward to assist the other fire dragons in dispersing the Dementors.
