Marvel's master of cosmic magic-Chapter 600

Fairy Tail had long since become the strongest mage guild on the continent of Ishgar.

Its influence stretched far beyond its borders. Powerful mages gathered under its banner, ties with the western Alvarez Empire remained strong, and even the Magic Council had learned to tread carefully. At most, they sent sharply worded letters. Gone were the days when enforcement squads dared to storm the guild and impose punishment.

When damage did happen, Rowan Mercer didn’t dodge responsibility. If it was his guild’s mistake, he fixed it. Quietly. Efficiently.

Originally, he’d believed that turning Fairy Tail into the top guild would mean peace. He could sit back, collect rare spellbooks, and deepen his research.

Reality disagreed.

After years of exchanging knowledge with Zeref and Mavis, and acquiring nearly every major spell tradition from the western continent, Rowan had already mastered close to ninety percent of the world’s known magic. The handful of techniques he hadn’t learned were rare outliers.

What he had gained in abundance was trouble.

With Natsu, Gray, and Erza as role models, new recruits learned fast and caused chaos faster. Their growth was impressive. Their collateral damage matched it.

Rowan had started considering handing the position of guild master back to Makarov once he dealt with the Black Dragon.

"Restore," Rowan said calmly.

He had just arrived in Agalifa City. With a single spell, half the ruined city rewound to its original state. Walls reformed. Streets straightened. Life snapped back into place.

Instead of returning to the guild, he cast another spell.

"Trace target: Ultear."

If he was stepping down, someone had to manage recovery and aftermath. Otherwise, Makarov would come knocking every time something exploded, without the slightest shame.

The repair mages in the guild were competent with small-scale damage. Cities were another matter.

Ultear Milkovich was perfect.

Former Grimoire Heart mage. Immense magical reserves. A master of time-based magic. Not restoration in name, but close enough in function. With training, she’d be more than capable of handling the disasters Fairy Tail specialized in.

Natsu might destroy buildings, but sinking a continent was still beyond him.

"Found you."

Rowan followed the glowing marker south, to the far edge of the eastern continent.

Ultear and her adopted daughter, Meredy, were in the middle of dismantling a minor dark guild.

Ultear raised crystalline constructs that shimmered with future light, unleashing a devastating barrage that dropped dozens of dark mages in seconds.

Meredy followed, her emotion-based magic surging outward, collapsing the remaining resistance.

Rowan descended just as the last enemy fell.

"There’s another one!" Ultear snapped.

Both she and Meredy attacked instantly.

Their spells vanished mid-flight.

Rowan lifted a hand. The magic dispersed as if erased from reality.

"Easy," he said. "I’m not with them. I’m Rowan Mercer. Guild master of Fairy Tail."

Seeing them tense further, he shifted into his familiar cat form.

Ultear froze.

"It really is you."

She’d seen that form before, years ago, during his work with the Council. The strongest guild master on the continent didn’t need introductions.

"What are you doing here?" she asked cautiously.

Rowan didn’t waste time. "I’m here to invite you both to join Fairy Tail."

Ultear and Meredy exchanged a look, then shook their heads.

"We want that," Ultear said honestly. "We want to atone openly. But the Council still has warrants out for us. Joining Fairy Tail would only cause trouble."

"I’ll handle the Council," Rowan replied. "If you join, you do it openly. You take jobs. You hunt dark guilds. No more running."

The charges against them weren’t unforgivable. The original Council was long gone, and Rowan’s influence carried weight. Enough weight.

After a long silence, Ultear nodded.

They returned with him to Fairy Tail that same day.

That night, Rowan left without telling anyone.

This fight was his alone.

Against the Black Dragon, no backup mattered. Its devouring magic nullified all others, even Zeref’s. Bringing allies would only put them at risk.

More importantly, Rowan trusted his strength.

Ankhseram, the god of death, was another matter entirely. The deeper Rowan dug into ancient records, the clearer it became that Ankhseram might not be a god at all, but the architect of this world itself. A being tied to the laws of existence, not merely death.

That was a battle for another day.

The Black Dragon, powerful as it was, still stood within reach.

Rowan stepped forward, alone, and began his march toward the final hunt.
