A gothic fae who's passion is making robots and other miscellaneous devices in order to help other dragons. Culet is his coworker, best friend, and boyfriend.

He has self-confidence issues, and often worries that what he's doing isn't good enough for everyone. He struggles with making sure he's indulging in his hobby for his own personal happiness rather than to please everyone he makes things for, and is afraid of leaving his customers unsatisfied alongside being taken for granted.

Whenever he gets too caught up in his worries and self-doubts, Culet helps de-escalate his emotions and bring him back down to a stable state of mind, before giving him words of reassurance and encouragement. Even when Culet isn't around in the moment to help, Gallium does his best to remember and keep his friend's words in mind. Together, the two are working towards making Gallium more confident in himself and his abilities.
