Theo showed a reluctant expression, but a part of him wished to tell his story to the girl who was staring at him fervently right now. After much consideration, he finally decided to spill the beans.
"It happened when I provoked a.. stronger dragon, one that was much more powerful than me and Tertia combined. I was supposed to receive the retribution.. the dragon attacked me, but Tertia shielded me from the venomous attack and the dragon's chaotic element ended up infusing with her core. She was unable to fully repulse the influence it brought, so her condition ended up worsening with time, and blindness.. happened. She always tried to make it seem like she was unfazed even right after the incident occurred, but I know! I have been paying close attention to her all this time, so I know," Tears threatened to spill out of Theo's eyes as his eyes shook.
