Wikipedia Trails: From Hades to Ariadne

1. Hades. Hades is the god of the underworld and abducted Persephone. He was not necessarily portrayed as evil, but came off as stern or cold instead. His priority was making sure no one left the underworld and was apathetic towards most of his subjects, though there were some exceptions.

2. Tartarus. Tartarus is a place in the underworld. It is where people received divine punishment and where souls were judged. Tartarus only served as a prison to those who could possibly harm the gods of Olympus. The place is referred to in popular culture, such as book series or video games.

3. Minos. Minos is one of three judges of the underworld. He is the son of Zeus and Europa, though he was adopted by Asterion. His name is said to mean "king".

4. Ariadne. She is the son of Minos and associated with mazes and labyrinths. In some versions, she is married to Dionysus, though there is a debate on whether she is a mortal or a goddess. She is known for helping Theseus.
