She knew that voice

A spell in the shape of a butterfly fluttered in the air. The sights around it came through in blurs, meshing together with odd echoes of sounds. It was not only difficult to navigate but difficult to discern the information that came through it.

Huo Tang at first only noticed bright glares of dancing light and something that sounded like the distant pounding of drums. A distant caw. A howl, perhaps. The butterfly continued to flutter toward the manor. There was a thick barrier in the sky, snaking and permeating in the air, preventing the butterfly from flying directly ahead. 

It took Huo Tang a moment to realize it was smoke.

But she couldn't quite pinpoint where exactly it was coming from, the spell too unrefined to give her sharper visuals or clearer sounds. But strangely, she could feel an oppressive force that came upon her like a thick wave.
