Amor is one of the last angel's occupying Earth. He is called back to Heaven, for a task, that will take him to the depths of Hell in search of his father who has been deceived and taken by Satan.
Heaven is a beautiful garden, filled with wondrous blossoms and various other flowers. It symbolises a perfect and peaceful world, occupied by angel's, an everlasting spring.
Hell is a lost world, concealed within thick icy snow, and flowerless trees. It's a place of darkness and depression.
"For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment." 2 Peter 2:4.
