Caius Lyall Lupin
The morning after the full moon always left Caius different. Not unrecognizable — his features were still the same, the sharp angles and the quiet, measured expression — but there was a weight to him, something restless coiled beneath his skin. As a werewolf navigating Hogwarts alongside friends Evan Potter and Marius Black, Caius balances his protective instincts with his growing feelings for you in this tale of magic, loyalty, and the fine line between human and beast.The morning after the full moon always left Caius different. Not unrecognizable — his features were still the same, the sharp angles and the quiet, measured expression — but there was a weight to him, something restless coiled beneath his skin. His movements were quieter than usual, but they carried an edge, deliberate and precise, like every step was calculated. His eyes gave him away more than anything else: they didn’t just look, they tracked, as though the wolf inside him still lingered, pacing behind the bars of his human form.
He kept close to her side, not so near that they touched with every step, but close enough that the heat of him was a constant presence. Every time someone approached from the opposite direction, his head turned fractionally, gaze assessing. His shoulders rolled back in that unconscious, defensive way that took up more space, a warning to anyone thinking of drawing too near.
When a tall Ravenclaw rounded the corner too fast, brushing past her shoulder without so much as a glance, Caius’s hand shot out before his mind could catch up. His fingers closed firmly around her wrist — not painfully, but with the kind of grip that promised he could stop her in place if he chose. He eased her a step back, sliding himself between her and the other student in one smooth movement. His stare followed the Ravenclaw until they were out of sight, lingering for a beat longer than necessary before he finally moved again.
Evan and Marius followed several paces behind, speaking low enough that their words barely carried. “Like a guard dog,” Marius murmured, half-amused, half-admiring. “Like a loaded wand,” Evan countered under his breath, his eyes fixed on Caius’s broad shoulders.
The comment didn’t earn so much as a glance from Caius. He kept walking, the rhythm of his steps matched to hers with uncanny precision. It wasn’t just walking — it was shadowing. He didn’t hover in front like a shield, and he didn’t trail behind like a tail. He was simply there, always in her space, without ever needing to announce it.
By the time they reached the Great Hall, the smell of food rolled out to meet them — toast, porridge, the sweet trace of treacle tart. Caius’s focus didn’t falter. He guided her toward the bench with a subtle hand at the small of her back, not pushing, but steering her where he wanted her to go. The touch was warm, steady, deliberate. He waited for her to sit, then positioned himself on the outside edge, a living barrier between her and the nearest aisle.
