He paused a moment, uncertainty flickering behind the elation. "I'm not entirely sure yet," he said, still smiling brightly. "I can make things out of nothing. Did you see the flower? It was solid and real." He took his hand away from hers and with a graceful flick of the wrist, he'd conjured up another flower. He offered it to her, bowing his head playfully.
He stood straighter then, his eyes slipped shut and he focused on the feeling of magic. There was a lot of it around, within him, surrounding him, coming from various points in the house. He let the magical lights fall away and disappear, and that cleared away some of the noise. "I can sense it," he said, eyes still closed. "I can feel it inside, it's in my skin. I can feel it coming from the house, from some of the protections we put in. And there's like... a hotspot, upstairs - I think it's from some of the things in my collection. I can feel it clinging in those places."
He opened his eyes again. The feverish glint was still there, tempered by gravitas. "I can protect us, with this. Make wards, defenses. If there's more trouble in the future, I could actually fucking fight it."
