Not all who reside in the Underworld are wicked. In fact, it is those who fight in the enemy territory and get their hands dirty that are the true heroes. The dark angels are the noble guardians of the Underworld. They make sure that it is run smoothly and that the savage demons of the Pandemonium are kept out. However, every now and again Lucifer, the leader of the Pandemonium, wages wars on other Underworld sectors and even devises plans of all-out attacks on the Utopia, the final resting place of the souls of the deceased. Now with the tension and conflict building up again between the Underworld leaders and suspicions rising, nobody can be sure of what the near future holds. A handful of dark angels of the Underworld begin to question their own allegiances and those of the individuals they deem as friends. Adelais, one of the dark angels, is worried that his friend, Malakai, from another sector, might be somehow involved with the recent mishaps. He finds himself torn and often clashing opinions with his superiors. At the same time, Malakai is faced with tough decisions and needs to choose carefully who to trust and who not to. Who could be responsible for stirring up the conflict again and what was their motive? Could it be Lucifer about to execute one of his schemes? Are the extreme times of a full-blown war about to come to pass? Decadence is the first book in the Melancholy Wings trilogy
