teleporting Unicorn

My Knight, came Mab’s psychic voice. We have perhaps sixty seconds before the Eye is once again loosed upon us. You must call her by then.
“There’s an army between me and there,” I protested. “Literally, an army.”
Gee, thanks, Sir Obvious, came the Winter Lady’s merry, excited, somehow panting psychic voice. I caught a glimpse of Molly across the battlefield, watched a heavy axe shatter upon the frost glittering upon her skin even as she flicked her white sword left and right with almost delicate motions, the lightest touch of the blade engulfing each of her foes in the obdurate ice of Winter’s heart. The smile on her face made her look wild and terrible and delighted, as the mountainous group of trolls behind her shattered each frozen foe to ice cubes with vast sweeps of their crude weapons.
There was an enormous exhalation, and the Winter unicorn suddenly stood in front of me, stamping its spiked hooves impatiently.
Mab took the psychic phone back, her thoughts mildly reproachful. Have I ever asked you to accomplish an easy task, my Knight? Tonight seems an unlikely place to begin.
Well. She had me there.
Butters, evidently, was not privy to Mab’s conversation with me. He was staring at the unicorn. “Uh. Harry?”
“Dammit,” I muttered.
I swallowed and took a deep breath. Then I seized the unicorn by the mane, hoped to God it didn’t notice how much my hands were shaking, and leapt onto its back. I turned back to Butters and offered him my hand. “No time. Trust me.”
