Whoom-!
The Territory shuddered as it faced the two attacks. The contradiction in rules made the green hue swirl violently. How was it to keep Ryolu out while not preventing Opportunity from leaving? Due to the simplicity of the Territory there was no backup in place for this very conflict of rules. Thus, the absolute rule of 'anyone is allowed to leave' overwrote the 'none shall enter' and created a hole. Its size was no larger than Ryolu's breath attack or the punch from Opportunity. Moreover the hole was already beginning to close, but not before the two Dragons slipped through.
Kan'na snapped her fingers and a magic circle entered the closing gap before it closed entirely. It spun rapidly as mana swirled from either side of the territory. With a smile she informed Yielya, "I got it."
