Ichor

Ichor is the fluid that flows through the circulatory system of divine beings (deities and daemons) instead of mortal blood. Having a blood-like consistency, ichor is golden in color, supernaturally glows, and (according to the more vampirically inclined beings of the palace) does not taste as sweet as mortal blood does, being much healthier composed.

Within divinities, an exception to this anatomical rule is the daemon Ker, Goddess of Violent Death. It is unclear whether the fluid inside of her, or usually pouring from the many open wounds constantly opening and reopening on her body, is actual mortal-grade blood or just red-toned gory ichor, but it shares none of the appearances of typical ichor and looks much closer to the blood found inside mortal humans.

Libitina, a loosely divine entity, is another exception to this anatomical rule - though she is... uh, most likely a goddess, she contains no ichor in her veins. This is moreso due to the fact that she has no veins, nor internal organs or fluids other than a viscous black mystery material. It is unclear if this is some form of ichor or some sort of specialized Libby... juice. Libby and Ty's child, Viduus, is presumably anatomically the same.
