Nathan jolted in surprise as the dark mist suddenly materialized, out of which a woman's figure emerged. She was wearing an ethereal-looking, long, dark dress that cascaded to the ground, and her shoulder-length, wavy blonde hair glowed against her pale skin.
"Rowena?" Nathan muttered under his breath, saying the name of the woman he had previously seen in the system.
Then, several bats enclosed in black energy burst out from under the ground, quickly multiplying until the fog had engulfed them completely. Dozens of bats flew in unison towards Linda, causing her to frantically dart around, her eyes blazing with rage.
"Mr. Nathan, that is Undead!" Meriel exclaimed in shock as the figure who had identified herself as Rowena appeared.
The spellbook "The Book of Darkness" whispered to Nathan, drawing him in with its ancient magical spells. It proclaimed its loyalty to him, offering itself as a devoted companion.
