The dread power of Thoth-Amon achieves devastating new heights as the young sorcerer sets in motion a plan to place the kingdom of Stygia within his serpentine grip. Having ingratiated himself to a weak-willed heir to the crown, Thoth undertakes the systematic elimination of any who would stand in the way of the fool's ascent to the throne. Yet there is one in the Order of Ibis who grows suspicious of Thoth's solicitous relations with the prince and the increasing amount of royal blood mysteriously spilled. Will this young priest discover the truth about Thoth in time to save the king, or will the snake-god Set sink its fangs into the last, best hope for peace in a war-torn land? Conan's greatest adversary matures into a mighty doer of evil in this penultimate issue of the series chronicling Thoth's origins for the first time!
