Ichor

Ichor was the golden fluid that flowed in the veins of gods and immortals, in Greek mythology. It was also believed that it was toxic to mortals, killing them instantly. Ichor also ran through the single vein that Talos had, a giant bronze man with wings that was seen in Ancient Crete. He was responsible for guarding Europa and hurled rocks against anyone who came close. He died when the Argonauts went to Crete after they had retrieved the Golden Fleece; Medea removed the nail that controlled the flow of ichor, which drained from Talos and killed him.
