Cyril manages to look a little amused at the idea of an exploding puzzle box. Because she's considering them now, he answers the question about them first. He can tell her who helped him with the explosions after, if that was what she meant instead.

"I used to make little toys that you could twist the pieces together or lock in and lock out for Merrick," he admits. "They helped him focus. You know, during his fits..." He's never really been clear on how much Beleth knows about Merrick's darkest moments. Most of the time, Pel and Cyril would take him away from the Clan for the duration and help him focus and calm down. They were never frequent enough to be a huge concern for safety, but the fact that they happened at all probably gave Beleth's mother more reason to consider banishing Merrick even before they had all left for the Inquisition.

"These puzzles are the same principle, only more complex. I took some of the training I had as an Artificer and applied it to the simple concept but added more layers to the device." After a moment, he adds, "I gave one to Cade. I thought, if it could help Merrick maybe it could help him too. I'm not sure how much he's used it."
