Arcanum Bellum: De Gloria et Excidio by William Ubagan is a gripping epic of mystical warfare, betrayal, and divine justice—set in a world where spiritual forces collide with earthly ambitions.

In an era of hidden powers and ancient oraciones, two opposing factions—one led by the righteous Lukas under the guidance of the wise Maestro Agedon, and the other by the ruthless rebel Marko with his dark spiritualist Tamarak—clash in a brutal struggle for domination. Through the secret knowledge of angelic and infernal forces, both sides wield esoteric powers beyond comprehension, engaging in battles that transcend the physical and enter the spiritual realms.

But amid the chaos, a shadow moves unseen: Homer, a master spy planted deep within enemy lines, whose allegiance remains cloaked in mystery until the final, fateful confrontation.

As blood is shed in the desolate "Land of Death," and as divine light battles the darkness of sorcery, the ultimate war unfolds—not just for land or power, but for the very souls of men.

A novel written in biblical tone, infused with authentic oraciones and ancient invocations, Arcanum Bellum explores the eternal struggle between good and evil, loyalty and betrayal, destiny and free will.

This is not merely fiction—it is revelation cloaked in story, for those who dare to see the unseen.
