Sanguines
Sanguines are dragons affected by a vampiric curse known as Bevitore di Sangue. There are two different kinds, Luna and Eclisse. While both variations exhibit the brilliant red wings and markings, Luna Sanguines have pale scales and skin, while Eclisse have dark scales and skin.

Any breed may contract Bevitore di Sangue, as well as any element, though Plague, Earth, and Light dragons tend to be most prone. it should also be noted that ancients who contract the curse are generally more feral than modern dragons.

Luna
The pale coloration of Luna Sanguines is from the many generations this branch of the subspecies has lived underground and in caves. like many cave creatures, color was no longer a necessity, and only the red of their wings and markings remain as a sign of their curse. Other predominant features of Luna Sanguines are poor eyesight, as they've evolved their other senses, such as hearing and smell instead to adapt to finding prey underground. They are also much more sensitive to light than their Eclisse counterparts

Neomenia
"Neomenia Sanguines" or "New Moon Sanguines" are those with Bevitore di Sangue who've fallen into a permanent blood-craze. A blood-craze is when a sanguine loses all sense of reason & rationale and acts solely on hunger and instinct, attacking any creature it can find and draining it dry of blood. They cannot speak or otherwise communicate, and are terribly ferocious. Most of the time, this is simply a phase that lasts only until the sanguine in question has eaten its fill, but this isn't always the case.
