Black Library - Ahriman: Undying

In Ahriman: Undying, the fifth installment of John French's acclaimed series, the once-mighty sorcerer of the Thousand Sons, Ahzek Ahriman, finds himself adrift on the precipice of time and space. Having located the fabled Key of Infinity—a Necron artifact of immense power—Ahriman's moment of triumph is overshadowed by his profound isolation and the remnants of his shattered ambitions.

Betrayed and bereft of allies, he stands amidst the ruins of his grand designs, with his Legion consumed by the fires of the Pyrodomon. To secure any hope for the future, Ahriman must confront the fragmented echoes of his past and navigate the perilous remnants of his former glory.

This paperback edition, released in 2025, continues the saga of one of Warhammer 40,000's most complex and enduring characters, exploring themes of redemption, loss, and the relentless pursuit of destiny.
