Those whose calling increase the number of dead are seen favorably. The Erinnyes are welcomed guests. He is exceedingly disinclined to allow any of his subjects leave.

Some Other Information
Hades was the God of Death and Dead. Hades was devoured by Kronos as soon as he was born, along with four of his siblings. Zeuslater caused the Titan to disgorge them, and together they drove the Titan gods from heaven and locked them away in the pit of Tartaros. When the three victorious brothers then drew lots for the division of the cosmos, Hades received the third portion, the dark dismal realm of the underworld, as his domain.
