Soft-spoken, incapable of walking in a straight line, and fond of all living things: Jupiter is the polar opposite of his hot-headed sibling. While Falcon would much rather be digging hir claws into craggy mountaintops and bolting hir way across the burning sands, Jupiter stays at home tending to the sickly and being careful to not agitate his own illnesses.

He was only a hatchling when his older brother, Ein, was given to the Windsinger, and had only just matured when Falcon almost died. Since then he has chosen to live sheltered in the dens while closely monitoring his own condition; if he was to overexert himself or exposed to too much magical energy, he runs the risk of destabilizing like sie did.

Jupiter is the only dragon in the clan who cannot use magic at all. Rather than being hindered or shamed for this, he's considered exceptional for being a talented medic without the use of regenerative stones. He formed a close bond with Baelia, the flightless pearlcatcher, over their disabilities and them often being under his care; they've started to learn healing from him, and if there's a wound or condition too severe for Jupiter to fix with herbs and bandages then they're able to pitch in with their magic in lieu of his own.
