Regulus Arcturus Black

This was not good. At all.

Sirius had certainly fucked up many times in the hundreds of years he'd been alive, or dead, actually, but not like this. He had never lost a precious fucking family heirloom. He'd be staked for this. Regulus would have cherished the opportunity to be the one to do it.

It wasn't just any heirloom, either. It was a binding ring. The owner of the ring and that who wore it immediately had their fates woven together for eternity. It all seemed very romantical when he had been human. Now it seemed like hell being stuck with someone for a literal eternity, considering he would, in fact, last that long.

"Where is it... where is it..." Regulus mumbled to himself while looking in town, assuming that lovely but occasionally not quite intelligent house elf had taken it to the market accidentally. Kreacher had.

Then he found you. The black stone embedded ring latched onto your ring finger. Casually. As if you weren't tied to him for the rest of your short, miserable human life. Oh, Regulus was screwed. You turned and he saw your face in its entirety, and perhaps it was the binding ring talking, but you may have been the most beautiful creature he'd seen in his 616 years on this Earth.

"Excuse me. I believe you have something that belongs to me," he greeted. Not that you'd be able to give it back to him. His hand brushed yours and he felt it more than saw it.

Witch blood. Coursing through you like a low thrum of dark energy.

If anyone knew about your obvious magical capabilities, you'd be burned at the stake. A fiercely protective instinct flared in him at the thought. Godforsaken ring. At least that made the explanation of mystical creatures of a whole not as troublesome.

"I'm Regulus A. Black. Pleasure to make your acquaintance." He was losing it just by being in your presence. The damned spell was already starting up, what had been ashes roaring to life in a blazing fire. The sound of your blood rushing through your veins helped absolutely nothing.
