Should I chronicle the war, then? Start with the alien Cielcin howling out of space in ships like castles of ice? You can find the war stories, read the death counts. The statistics. No context can make you understand the cost. Cities razed, planets burned. Countless billions of our people ripped from their worlds to serve as meat and slaves for those Pale monsters.

The Cielcin are a spacefaring, humanoid, and carnivorous alien species featured in the Sun Eater, a science fantasy series authored by Christopher Ruocchio.

Anatomy and Physiology

Physical Attributes

“They have six fingers!” I remember saying, reaching up to transfix the holograph with a finger. “Why do they look like us?” — Hadrian Marlowe [2]

The Cielcin are a tall, pale, bipedal species whose bodies look eerily similar to humans but are unmistakably alien. At full maturity, a Cielcin stands between seven and nine feet tall, though their rapid development means that even the children stand taller than most adult humans. They are long-limbed, with narrow bodies and arms that reach almost to the knees when standing upright [3]. As the human slur "the Pale" suggests, their skin is milk-white, smooth and hairless, except for the back of the head. There, thick, white hair grows beneath an epoccipital crest of bone, often referred to as a "crown", that rises from the forehead, sweeps backward at a steep angle, and terminates just past the ear holes. Scale-like lumps of skin are present where the forehead transitions from smooth, white skin to the bony ridge of the crown and horns. Some captives have been seen with their horns sanded or cut off, leaving rounded nubs at the brow [2][4][5].

Cielcin eyes are black, unfeeling, and the size of tangerines, set in a smooth facial structure that lacks an external nose or ears [6]. Instead, they breathe through four narrow slits where a nose should be, and sound travels through small holes behind the horns [4]. When bared, their too-many teeth appear sharp and clear as glass, set in black gums, and their long tongues are a dark blue-black color [5]. Similarly, Cielcin tissue has a bluish hue, with dark blue-black, ink-like blood. Glassy too are the nails on Cielcin hands, each with six fingers, thin and many-jointed [2].

Their physiology appears adapted to darkness. Scholiasts correctly theorize they are a subterranean people, a view supported by their cavernous, unlit oscianduru (worldships) and their ability to see well in low light [5].

Reproduction

Within their species there is little sexual dimorphism; the Cielcin are hermaphroditic and display no cultural modesty or division of gender [3]. Cielcin are mono-sexed but with twin roles: akaranta (active) and ietumna (passive). They reproduce parthenogenetically, able to conceive without fertilization. The embryo is initially a genetic duplicate of the parent. This embryo can then be implanted in another Cielcin, whose biology alters it through a process called conjugation, which combines traits from both parents. The host may then transfer the embryo again, producing offspring with genetic material from multiple parents. Throughout the Cielcin Wars, it was also proven that humans can serve as viable hosts for Cielcin embryos, though such pregnancies are fatal [7][8].
