Lumina are one of the many fish species native to the Lumicryst Region, specifically inhabiting the vibrant Lumicryst Lake. They are best known for their stunning bioluminescence, which adorns the sides of their bodies and their fins. Lumina come in a dazzling array of colors, with several notable variations: the Zyon Lumina, with a pink base, purple subcolor, and blue-glowing fins and bioluminescence; the Elior Lumina, entirely purple, including its bioluminescence and fins; the Pink Horizon Lumina, which is uniformly pink across its body and glow; the Golden Crown Lumina, featuring a gold base, orange subcolor, orange fins, and yellow bioluminescence; the Sunset Lumina, with an orange base, magenta subcolor, and yellow fins and bioluminescence; and finally, the rarest of them all, the Black Serpent Lumina, with a black base and subcolor, complemented by striking red bioluminescence and fins. Lumina live in large schools of up to 100 individuals, often featuring a variety of colors. Despite their small size, they are incredibly fast swimmers, making them difficult to catch even for trained professionals.
