"Prince of Darkness" tells the story of Lucien, Valdara's firstborn prince, falsely accused of crimes by his stepmother Queen Seraphine and exiled by his ailing father, King Halric. Wounded and betrayed, Lucien escapes into the perilous Hollowshade Wilds. There, he's rescued by Vaerin, a mysterious, blind warrior who teaches him to survive the cursed forest and its sanity-devouring magic, forging him into a formidable figure. As Lucien undergoes a dark transformation and learns of the forest's ancient origins and its monstrous guardians, he confronts the first beast, the Hollow Stag, and claims a powerful artifact. Meanwhile, in Valdara, Seraphine and Renard consolidate power amidst King Halric's fading health and growing regrets, unaware of the reckoning that is about to emerge from the shadows of Hollowshade.
