(I figured that an AMA would be the best way for me to catch holes and address intricacies in my magic system, before I go nuts with it in my work in progress) Within the World of Ethyes, the dominant sentient race are the Apsara. They are mostly human in appearance with three notable differences. They're hotter, age 1 year for every 3-5 years that we do after the age of 20, and they have miniature "stars" (Khei/Microcosm) in their eyes. In the middle of the "star", where the pupil should be, is a white "black hole" (Kheria/Core). Anything that enters the eye's black hole becomes part of the Khei. This is mostly through the bloodstream, but there are rather gruesome ways around it. Once something is part of an Apsara's Khei, the Apsara can use the Khei's "starstuff" to regenerate a copy of the substance within the Khei and send it to any part of the bloodstream (mostly the fingertips). This can include window cleaner, alcohol, heroin, detergent, and powdered metals. But the Khei cannot generate energy, for that power belongs to the Mahoragas. The eyes (which can be blue, silver, gold, bronze, or red) glow during the generation process. However, most things that get in the Khei will be destroyed unless it is coated with 'catalyst blood' prior to its entry into the body. Catalyst blood protects the fidelity of the substance in the bloodstream while neutralizing the most dangerous effects. Catalyst blood can also be used to safely coat and expel substances outside of the body. To create Catalyst Blood, an Apsara only has to process blood into their khei to convert it. However, the effects of Catalyst Blood only last for a minute and become Dhukka afterward. Dhukka cannot be expelled out the body through normal means, since can't separate itself from blood like Catalyst Blood. Dhukka can however be used to create more Catalyst Blood, but if Dhukka is left in the bloodstream for too long, it becomes Mara, a poison that slowly destroys the Khei.
