Once a Demigod reaches their early teens (or the non-human equivalent,) they release a scent that some monsters are able to detect. The strength of this scent varies depending on the strength of the godly parent; a minor deity's scent is more muted, but the scent of the Big Three gods - Zeus, Poseidon, and Hades - is much stronger. This scent can be masked through various ways, but once a demigod learns that they are descended from a god, it is much harder to control. The Mist shrouds these monsters from most mortals, but they will stalk their prey until they are destroyed. That is why there are various safe havens created for demigods to be brought to, where they can live in peace among one another. Many demigods have no knowledge of their lineage until they are attacked, which makes for a very jarring transition. Some demigods do choose to leave their safe haven and live in the mortal world for part or all of the year, but it can be very dangerous to do so.
