"What kind of problem?" Leon asked, suspicion written across his face as he narrowed his eyes at Rees.
"Umm… you see," Rees began, rubbing the side of his skull. "The teleportation spell I intend to use… it consumes a massive amount of mana. On both ends."
"Both ends?" Leon repeated with a confused look. "What do you mean?"
"Aha… well, that's another part of the issue," Rees said with a nervous chuckle. "This spell works using two magic circles—one drawn where we are now, and one drawn at the destination where we want to teleport."
Leon crossed his arms and raised an eyebrow. "Something tells me the problems aren't over yet."
"T-There might be… one last, very, very small issue," Rees said sheepishly.
Leon's voice sharpened. "What is it?"
"If mana isn't supplied to both circles at the exact same time… the spell fails. There's only a one-second window to ignite both circles and if-"
"…And if it's not done simultaneously, it won't work," Leon finished the sentence with a sigh.
