Essence
In his sixth year, Draco reaches for the only shard of sanity he can find, and puts his desperate faith into magic, the thing that has always set him apart as a pureblood wizard. The magic he unleashes though, is old, powerful, and maybe even more desperate than Draco himself, to leave an essence of life behind.
The little bump isn't what he needs to carry out his mission, but it might be the thing that saves him.
