"If it needn't be permanent," Carlisle replies, thinking aloud, "then perhaps an imbued tea would be the best way to go. We'd have to test it, of course, as a magical drink might not interact with your particular anatomy and energies quite as readily as I can on the manual level, but that might be a way to, at the very least, mitigate some of the inherent problems with you slipping into a warm bath."

He slows down, trying to manage his thoughts; they're still frantic from his relative lack of sleep, and therefore harder to control. "Al- although perhaps it'd be safest if I just took a cold shower instead. Much simpler."

Simple, yes, but not nearly as relaxing for his stiff joints and aching forearms. His need to water his garden through magic has only exacerbated his condition over time, and with each month that goes by, it gets harder to pretend that he's not hurting. His plants only needed minimal watering when in the cool comfort of the cave, but on this world with multiple suns, the only way he's managed to keep his garden green is by ensuring his various shrubs and vines never go thirsty.
