On the ground, in the north.
Around a vast city in the wilderness, a fierce battle was underway.
The Blue-robed Wizards from Deep Blue Castle and the Black-robed Wizards from the Mysterious Organization were the attackers, while the defending wizards, dressed in various organizations' robes of different colors, were the defenders.
Because it was an ambush, the attackers gained a considerable advantage from the start. Flames, Wind Blades, and Ice Cones were furiously shot into the city, and within a short time, they had occupied nearly half of the city, with the battle line constantly pushing deeper into the city.
The defending wizards, caught off guard, couldn't organize an effective defense line and could only retreat. As defeat seemed inevitable, a few wizards with a strong presence appeared, flying out from the city and blocking the attackers' path.
