"My friend, she's not lost to you, yet.."
But she would be, if he didn't act quickly. Xaver winced slightly, but shook it off, planting both hands, one over the other, over Uni's heart, focusing his will, and power, into the unicorn. Slowly, he became blinded to everything but the unicorn, and his power, his lifesource intertwining with Uni's. He gave her his strength, locking her onto it, and keeping her alive, as he focused further, his will searching her creature much as an antidote - finding the 'poison'. It took a while, and eventually Xaver's hands glowed with the sheer power it took, but slowly, one hand remaining on the unicorn, he lifted his other hand, liquid appearing in a stream through the light of his other hand, hovering above his palm.
Finally, the light dissapated, and he sort of sagged, resting on the unicorn's shoulder even as she slowly opened her eyes, looking around curiously.
Xaver rose, standing, liquid hovering in a sphere shape, between his hands, much like a water orb - but different. It was the potion, that had poisoned Uni. He looked at it for a moment, before he slapped his hands together, and the potion disappeared.
