After Jonathan left, Koby remained to look for his teacher. Instead of waiting at the shore, he decided to dive down and use what his teacher had taught him. He was still looking when an arrow tore through the sea and slammed into a hidden barrier.
Water escaped into the hidden dungeon, pulling Koby with its raging currents. As he realized where his teacher had gone, he also realized someone else was trying to find him. Koby vowed to protect the dungeon. Thus, he became its guard.
Koby realized his weakness as each of her arrows rendered him utterly helpless. They could not be blocked, diverted, or dodged. They tore through the hidden dungeon despite his efforts, making the mage despair.
In his moments of utter despair, a blue dragon emerged from the underwater fissure. A majestic creature that seemed to encompass boundless wisdom and strength began fighting against the archer woman, protecting his teacher.
