Xavier straightened in his seat. The shift in Rousseau's tone caught his attention more than the subject matter itself. The professor moved to the door and closed it, then returned to stand directly in front of the class.
"The Global Gate Authority recognizes seven official gate types," Rousseau continued, writing on the board. "Dungeon, Survival, Puzzle, Escort, Racing, Siege, and Mystery. Each presents unique challenges and requires specific strategies."
He turned back to face the class. "Dungeon gates are most common—linear progression, monster elimination, boss encounter, crystal reward. These represent approximately seventy-five to eighty percent of all gates."
Xavier leaned forward, resting his elbows on the desk. Something about Rousseau's demeanor made this feel less like a standard lecture and more like classified information.
