Roxanna stared at the changes happening to Sybill, her eyes filled with disbelief.
The black mist slowly wrapped around Sybill's body, changing her into something that no longer looked like a mermaid.
Her fish tail gradually turned jet black, while dark veins spread across the shimmering scales. The beautiful blue fins she had once been so proud of withered away, replaced by jagged, shadow-like fins that looked more like blades than part of a living creature.
Her long hair floated wildly around her as if it had a life of its own. Even her skin began to lose its healthy color, becoming pale enough to resemble a corpse.
"W-What happened to her?" Roxanna asked, unable to tear her eyes away.
Zeir's expression grew grim. "She's being corrupted. The black magic isn't simply giving her power," he continued. "It's changing her body to match the darkness inside it."
