A Shadows Journey: Prides Desire - A Shadows Journey, #1

How far would you go for your best friend? Would you cheer them up when they're sad? Would you lend them money if they need it? Would you be there for them if they are having problems at home? Would you go through hell for them? One boy named Shadow finds himself in hell after his best friend was kidnapped by a demon. Unsure where to go hell's vast wasteland he's found and trained by the original sinner Eve.
She determines that the ones most likely responsible for this kidnapping are the rulers of hell the "Seven Deadly Sins". With his training finished he sets off for the sins starting with Pride. Why? Because he's already in his territory. However, Eve thinks he should fight a different sin first since, from what she hears, Pride is one of the strongest sins. Along the way he meets two hellborn companions.
Lina, an outgoing devil that seems to know more than she lets on. She wishes to confront Pride for her own reasons. As well as Silt, a monster who's on his own personal journey. He was already planning to fight Pride when he met the Shadow. Although being wary of them, Shadow knows that it's better to fight along with them than alone. Between the Orthruses, the Dragon, and the sins of Pride Shadow really has a rough journey ahead.
Though with all of this one question remains. What is the true essence of Pride?
