The Scribe of the dying Sun. The Shadow Council, #1

In the heart of the Obsidian City of Amurru, the light of human wisdom is being extinguished by rivers of fire. Damien, the Royal Scribe and custodian of the city's most precious intellectual treasures, has spent his life anchoring humanity against the encroaching shadows of oblivion. But as a brutal siege crumbles the Great Archive and centuries of scrolls turn to ash, he is faced with a terror more potent than any invading army: the total erasure of history.
In the heat of the inferno, an ancient, primordial presence offers an impossible bargain. Damien can save the collective memory of his people by becoming its eternal guardian, but the price is the forfeiture of his humanity-the warmth of the sun, the comfort of touch, and the very capacity for mortal joy. Forged in the crucible of annihilation, Damien is transformed into the Sovereign Scholar. With skin like polished obsidian and eyes holding the cold light of forgotten stars, he begins a solitary vigil that spans three millennia.
From the rising pyramids of the Nile and the disciplined legions of Rome to the mechanical roar of the Industrial Revolution and the binary deluge of the Digital Epoch, he drifts through time as a spectral sentinel. The Scribe of the Dying Sun is a sweeping, metaphysical epic that explores the enduring power of memory and the profound sacrifice required to keep the light of knowledge from being lost to the silence of time.
For in the preservation of our collective memory lies the truest form of immortality.
