LOTS of time and patience. A pattern I use is Back,Jump,Jump,Repeat.
Charon
Hades
By paying coins to Charon the ferryman of the dead, to ferry you across the river Styx.
Charon the ferryman transported the recently deceased across the River Styx to Hades.
Charon
Hades is the ruler of the Underworld. Charon (not a god) ferries the dead across the river Styx into the Underworld.
For more or less the same reason Hades himself was: it was his job. If there's a river that you can't ford or swim across, there has to be a ferryman. Charon was that ferryman.
Charon is the Ferryman who takes people across the river Styx to Hades.
Acheron, the river of pain. The River Styx is usually the one referred to that Charon ferries the dead across to the Underworld.
Charon the ferryman brought them across the river Styx, which was the boundary between the upper and lower worlds.
I think you mean tartarus, no hades, Hades is the God that rules over the Underworld, Tartarus. The one the ferries souls across River Styx is Charon, but the one that guides the souls to him first of all is Hermes.
Not really a fisherman, but a ferry-man. Charon took the dead across the river Styx to reach Hades. The price was one obol.
