Zahir remained firmly stationed in his place of shelter, remaining immobile despite the drop persistenly falling down his neck. The key, he had learned, to not being seen, was not to hide in the shadows, or make oneself as small as possible. The trick of it was to not. move. No matter how tempting it may have become.
The steady thump and squelch of horse hooves passed him by, the sound nearly completely drowned out by the thunderous storm above. He waited a beat, then two, before stepping out of his shelter. Immediately the wind hit him, blowing his cloak out behind him as another crash of thunder and lightning lit the sky.
Vision. His eyes alighted on the drenched, ebony rump of the mare and he scowled. The mare was quiet and calm in the face of the storm, despite the unknown person walking beside her, and a quiet, seething rose inside him. Pushing his irritation at the horse aside for now, he moved forwards, his advance muted by the weather. For the first time, he was thankful for the storm.
He arrived behind the pair without a sound, his hand resting on Vision's hindquarters for a moment as he felt his way to the sword tucked into the supplies strapped to the mare's back. With a shrill ring of metal, Severus slid free of its casings, the sound sudden, sharp, and directly behind the figure still obliviously leading Vision onwards.
