How would i describe each three settings of the underworld in the lightning thief?

In "The Lightning Thief," the Underworld has three main settings: the Fields of Asphodel, the Elysium, and Tartarus. The Fields of Asphodel is a gray, dreary place where souls of the unremarkable wander aimlessly, reflecting a sense of limbo. Elysium, in contrast, is a bright and beautiful realm reserved for heroes and the virtuous, offering eternal rewards and bliss. Tartarus is a dark and terrifying abyss reserved for the wicked, filled with torment and punishment for those who have committed grave offenses.
