The Obsidian Manuscript 18+

When historian Elias Thorne deciphers forbidden symbols in a medieval manuscript, he awakens an ancient force and draws the attention of a murderous cult known as the Shadow Hand. Pursued across storied cities and haunted by whispers from beyond the veil, Elias must unravel a cipher that bridges time, architecture, and cosmic horror—before the next piece of the Obsidian Testament falls into the wrong hands.
