The Old Gods: Unwritten Realm. The Old Gods, #3

The Shadow Awakening tightens its grip on Xylos, and Regent Thia knows the source lies deep within the terrifying Unwritten Realm. Following the fragile Sign of the Labyrinth, she descends further into cosmic madness, leaving behind the last vestiges of reason and venturing into dimensions designed to break the mind and devour the soul. In the Geometry of Madness, the very landscape becomes a weapon, twisting into impossible shapes and perspectives that assault Thia's senses and erode her sanity.
Hostile entities, born of living geometry and pure shadow, emerge from the chaotic depths, forcing her to rely on instinct and desperate cunning to survive. But the true trial lies within the Gauntlet of Memory, a psychic labyrinth sculpted from Thia's deepest grief and guilt. Here, distorted reflections of Khepra and Seneset, and the decaying image of Xylos itself, torment her, pushing her to the brink of despair and offering the seductive solace of oblivion.
Emerging into the eerily silent Silent City, Thia finds a metropolis of impossible architecture, haunted by unseen watchers and permeated by the crushing weight of the Old Gods' presence. As Seneset's voice transforms from guide to tormentor, and time itself loses all meaning, Thia must navigate a treacherous path towards the towering Spire - the heart of the Unwritten Realm and the dwelling place of Azathoth's Whisper.
In this harrowing third chapter of the Old Gods series, Thia will be forced to confront not just monstrous entities and impossible landscapes, but the darkest corners of her own psyche. She must learn to trust her intuition, to weaponize her memories, and to find strength in the echoes of love and duty to withstand the overwhelming psychic onslaught of the abyss. But as the whispers of oblivion grow louder and the true nature of Azathoth's Whisper is revealed, Thia will face a choice that could save Xylos...
or damn them all to the silent, uncaring void.
