Everything seemed to happen in slow motion. Makka had either seen the thing or picked up on it's scent, because she whined and scrambled in his arms until he let her go. He thought she might run, but instead she turned and bounced on her heels, barking loudly; he even heard her growl a few times. He never would have considered Makkachin to be the brave type, but she was attached to him, and apparently she was not about to run and abandon him or Yuuri.
As soon as Makka tumbled out of his arms, he stumbled, tripped, and went down. He started to cry out (and automatically his arm went out to break his impact, because one of the earliest things a figure skater learned was how to fall), but he missed by a few inches and slammed the side of his head against a rock sticking out of the ground. The world went very still, and aside from the ringing in his ears, all sound ceased altogether. He had taken a lot of falls in his lifetime, and even hit his head a few times, but he knew immediately that this was bad. It knocked the wind out of him and he didn't even have enough breath to shout for Yuuri to run, because he wouldn't be able to live with himself if Yuuri was hurt because of him.
He could feel the air grow colder as the creatures - two of them - bore down on him. He lifted his arms in a very weak shield and last line of defense, but before they could reach him, he felt Domovoi block their path and flare his wings, screeching loudly. He was so tiny, and no match for creatures like this, but determined nonetheless, and he stood his ground in a brave defense; Viktor could sense (and later, would have time to appreciate) the fact that Dom was entirely willing to go down with him if it came to that.
He wasn't entirely sure what happened next, as the nausea he felt was almost overpowering, but the creatures were rattling and hissing, bearing down on Dom, who still refused to move; a bright flash of light he could not explain, and then suddenly the cold and darkness lifted, burning away like clouds under a morning summer sun. The creatures vapourized, turned to dust, and Domovoi was left standing.
Viktor vaguely had time to glance towards Yuuri, saw he was safe and whole, and surrendered to the blackness threatening to overwhelm him.
