Conan the Barbarian #50 (Marvel Comics, 1975)

In Conan the Barbarian #50 (May 1975), titled "The Dweller in the Pool!," Conan and his companions encounter the priestess Lupalina while journeying through the Border Kingdoms. Tasked with delivering a protective amulet to the puppet king Themas Herklar, Conan is magically teleported directly into the lightless dungeons of Castle Phalkar.

While exploring the subterranean depths, Conan discovers that the king is a broken man, held captive while a magical being of evil named Unos occupies the throne. The situation turns deadly when a swarm of subhuman creatures emerges from the shadows to attack. In the chaos, Conan must battle these monsters and find a way to return to his friends before the "Dweller in the Pool" can claim more victims.

This milestone 50th issue features a thrilling climax and marks a significant chapter in the Cimmerian's legend, brought to life by the powerhouse creative team of Roy Thomas, John Buscema, and Dick Giordano.
