Normally, Guy would have jumped at the chance to learn more about heraldry and what it could do for both weapons and technology, but at this point he merely filed the information away so that he could focus on the matter at hand. Even his love for fontech wasn't enough to distract him when a friend was in need. He hadn't quite realized that heraldry was something that could only be used by someone if they were born with the talent. That meant that most people in Auldrant probably wouldn't be able to use it as a replacement for Artes, but he'd think more about that later.

He frowned when Claude started to rub at his eyes, immediately deciding that that was a bad idea. While he was sure that those compresses were difficult to deal with, the younger man was only going to make things worse if he kept worrying at them. Guy wanted to tell him to hold off (or even pull his hands away himself), but then Claude kept talking.

So it was a light that had damaged Claude's eyes. That made it hard to know whether or not the damage would be permanent. It might be something that Claude could eventually recover from, but it probably depended on how strong the light had been. Then again, maybe there was a healer around who could help him out? If the eyes didn't heal on their own, it was probably something Claude would have to look into.

But it sounded as if even Claude didn't know what exactly had been done to him, which was obviously unsettling. Guy frowned at the foreign terminology, though. Whatever it was, it sounded bad. "What's DNA?" he asked, uncertainty coloring his tone.
