The Litch King Transformation?

When I try to focus my eyes to see the appearance of the person hidden within the darkness, all of a sudden, a powerful ominous aura enveloped the entire skeleton graveyard room, coming from the deep part of the room that made me startled and raise my guard.

Crkl* Crckle*

A slow step that produced a low cracking bone voice echoed throughout the silent, eerie, and dark skeleton graveyard room.

Step by step, the eerie step that produced a cracking bone sound that made people's ears in discomfort, slowly moving in our direction.

Before long, that step stop as the appearance of the mysterious person become visible after illuminating from the light which comes from the gaping cave wall I created before.

It was a man who has his body covered by a dark and dirty cloak.

His face looks very thin and pale as if it consists of his skull, covered with its skin, making his true human appearance became very vague, and more like a skeleton.
