There's two more things I'm also looking forward to, along the lines of what made Hades angry.

Ordinarily Hades was a more serious and less petulant god than the others, but there were two things that would cause him to fly into a rage and punish a mortal for all eternity far beyond the normal levels. One was attempting to escape the Underworld/betraying him (#Sisyphus).

The other was threatening Persephone. Pirithous was bound in a stone for all eternity for an attempt to steal her away. Whether or not a romance develops between them I'm leaving up to the game, but his interest in her safety will still manifest.
