The magic shoes are going so fast that Grover can't take them off, and Percy and Annabeth can't help him.
Then, Grover's magic shoes do something weird: they fly without him telling them to, and they drag him away from Hades's house toward a narrow cave.
The Furies are flying proud over Hades's house.
In the distance is a palace of obsidian towers: Hades's house.
They continue to walk through the Asphodel Fields for miles.
Percy realizes how few people in the world choose to do good things in their lives.
Elysium is way less populated than either of the other fields.
That's where heroes retire when they die.
Elysium has a beautiful blue lake, and in the middle of the lake are three islands: The Isles of the Blest, "for people who had chosen to be reborn three times, and three times achieved Elysium" (19.12).
In the other direction, they can see Elysium – a lovely gated community featuring "beautiful houses from every period in history, Roman villas and medieval castles and Victorian mansions" (19.10).
In the distance, they can see the Fields of Punishment burning "with rivers of lava and minefields and miles of barbed wire separating the different torture areas" (19.9).
The Asphodel Fields are HUGE, swampy, and dismal.
Now imagine a field a million times that big, packed with people, and imagine the electricity has gone out, and there is no noise, no light, no beach ball bouncing around over the crowd. Imagine the largest concert crowd you've ever seen, a football field packed with a million fans.
