3; the spirits poisoning you
They hear the voices calling to them from far beyond the veil, and they long to follow them, falling gracefully into the nothingness 'till they can't hear or see or taste or feel anything. They are not creatures of this earth, and everyone knows it. But they are destined to stay here, at least for now, in this world of wars and darkness and manipulation and lies. They will never feel the ripple of the cloth and the arching of their bodies as they fall, fall, fall; they will never see what lies beyond until it's too late – until every last drop of innocence has been drained from them, until they have been corrupted beyond repair.
And they restrain themselves from jumping, from following their ancestors and lost loves and everyone else into what might be a world of joy – or a world of pain. A world of love, or a world of hate. A world of difference, or a world exactly like the one they want to escape from at any cost.
Perhaps Harry and Luna will never know which.
