Then Veric sees the ruins of a gigantic underwater city. To top it off, sailors fall sick, one after the other... 5 - This World of Smoke: Veric and Sandrin set out for Uddengahl, a legendary and cursed land at the heart of the Krymean Crowns, hoping to find clues about Kurhen. But as they travel, a thick black smoke spreads across the land, bringing with it deadly visions. 6 - When Silence Speaks: As they approach Uddengahl, Veric and his friends discover they can no longer hear their voices, and can only communicate with their thoughts.
Their quest leads them deep underground, in the lair of monstrous creatures... These three stories introduce new characters, develop some of the main plots, ask new questions, and bring our characters closer to finding answers. "The Swarming Death" is a series of 12 high fantasy novellas that veers progressively into epic. Though it starts gentle, it grows in complexity and becomes darker with each new installment.
