The underworld was a dark and dreary place with mindless gibbering and shrieking human ghosts.
Even before Death ditched him to return to the sunnier and more pleasant upper world Damon had figured out that to 'rest' here would eventually leave him just another mindless babbling shade like the rest Death must have scammed into 'resting' here before him.
So as soon as Damon was safely sure Death had left the new doomed human ghost explored his surroundings and its occupants seeking a means of escape.
There were no non-human folk here and human wise besides the ghosts there were just as mad flesh and blood Greek heroes from the Trojan War who kept babbling " Beware the Minotaurs Eye"
Damon quickly gave up any ideas he had that the locals could help him escape back to the upper world and instead concentrated a search of the artifacts ,ruins and hulks that were scattered everywhere.
Besides half sunk sailing ships there were a few intact looking steamships moored in the harbour.
There were half demolished shopping malls all over the place and the mountain side had more then enough crumbling Roman temples and Dark Ages castles.
However it was the Space Ship,Galactic Star Cruisers and Station 45 Clubs Wrecking Yard
off to one side of the Mountain that gave Damon his first possibility of escape as it appeared some of these busted and dented space vessels might still be functional.
Where there was a functioning ship Damon might find a
Transporter or Teleporter that could return him to the upper world and possibly alien space empires as well.
