The blond who did find Sephiroth wasn't Cloud but Rufus on the hunt. As soon as he found himself in this strange world he had instantly gone looking for not only allies but for Sephiroth as well.

The accounts of a silver-haired man who laid waste to towns made his stomach sink. There was no sign of Cloud and his friends- he couldn't even find his Turks- so there was nothing he could do but to find Sephiroth himself. He may not be able to win the fight even with his powers but he wasn't going to run away.

The fires of the town were hot but he presses on, telling any survivors fleeing to get out of town, don't come back. It wasn't difficult to find Sephiroth himself and despite the fear that runs through him, he's not going to run.

"Sephiroth. What are you hoping to accomplish here?"
