Rune howled and leaped into the air, snapping his jaws over and over. To the accompaniment of Nidhogg’s booming trumpeting, Dewi shimmered and vanished. Fire flashed from Nidhogg, cutting a wide swath.“What’s the matter, Celt?” Adva sashayed to his side. “Lose something?”Fionn twisted, light on his feet, and smashed his fist into Adva’s face. He heard the crack of bones breaking and drew his arm back to do it again, but the dark god jumped out of the way. Blood and snot ran down his face, but the damage began to repair itself immediately.In a shower of fiery sparks, smoke, and steam, Nidhogg dropped to the ground a few feet from Fionn, his green eyes whirling furiously.“Goddamnit!” More fire flashed from the black dragon. “I told Dewi not to use the MacLochalinn bond to follow Aislinn. Ordered her not to, but she ignored me. Now she’s trapped too.”Nidhogg plodded toward Adva with fire blasting from his mouth. It rolled off the dark god like water, but his shirt and trousers smoldered.
