Hm. Princess Frosthair's palace is on the edge of the desert, buuut- perhaps her folk are well-versed in water-magic, and thus irrigation. This might be their pleasure-palace/proof of dominance over the thirsty sands (like Vegas!), with canals and boats so that even here, the royals can get fresh fish from the ocean. I like the image of the princess playing with a water-droplet, a bit like flipping a coin on your knuckles. I also foresee someone insulting her with the term 'fishwife'.
