I have two headcanon ideas about the crystal pendant, one heartwarming and one interesting. The heartwarming one: Xephos loses his pendant at one point and is absolutely devastated. Simon spends all of his free time for five whole days looking for it, until he finds it in the reactor room on the space station. The interesting one: Xephos's races eyes only light up on physical contact with these crystals: the pendants were sirst made in case of emergencies like being stranded on a dark planet.

Ohhh yess! I love both of these. I especially like the one about the physical contact. That would be very interesting theory.

Talking about Xeph’s eyes, I like the idea that his eyes get brighter when excited and duller when he’s sad/tired and that is mirrored in his crystal.
