the binding (слэш)

When Severus Snape performs a forbidden Familiar ritual to bind a mythical beast before the Second War, he expects a creature of fire and scale. Instead, his circle ignites with emerald flame — and Hadrian Potter appears.
Unbeknownst to all, Hadrian is the last of the Drakens — a half-dragon, half-human being once enslaved by wizardkind through this very ritual. The bond links them through blood, thought, and heartbeat. Severus becomes his master by law of magic, though the very act horrifies him. As the bond deepens and begins to equalize, control shifts — and affection replaces fear.
Together, they walk both sides of the war, bound in secret, bound by fate — learning that what began as a mistake may be the world’s last hope for balance.
