A relic

You see recently dracos luck took a complete u-turn when he found it, a hypno ring that quite literally landed in his lap

The ancient magical artefact was costly, to say the least, and this wasn't talking about gold. No, for instead the Hypnos Ring in Borgin & Burkes required… sacrifice of a kind; it had to be a meaningful offering to sate the ring. Not to mention, the sneaking around he had to do, in order to obtain the ring, without alerting anyone (particularly Dumbledore) of his intentions.

He was going to miss his right eye, even with the magical replacement.

But it was worth it, Draco told himself frequently. The gold-banded ring with its jade crystal rock, shaped in the form of a heart, caused his body to thrum with the power it possessed. It was this power that would make Potter pay and make Daphne Greengrass into his pureblood whore.
