Last call! All aboard!

The worst and most powerful curse is unsatisfied desire. It causes the worst kind of lust.
The adventurer had lost the count of the days and nights he had spent in that madness of lust. Of all the deadly sins, he was cursed with lust and laziness. But laziness was an easy path. Lust... lust obsessed him, darkening his mind's clarity until the entire world around seemed bathed in ambrosia and his mind wasn't able to go beyond his twisted senses. Then, when that happened, there was no hope.
The adventurer travelled on a train the windows of which were all curtain-closed. The rails formed a circle. The train didn't stop. He walked along the corridors while people were inside the compartments. He knew it, but the curtains never opened. He was condemned to just walk and try to look, never to get in. Just imagination.
The train that was his mind was lost in a perfect circle.
Then he saw a bright green spot on the horizon.
