Walking with Superman: Day 336

Superman comes to Decorah, IA, where the staff of the staff of the Vesterheim Norwegian-American Museum hope that his incredible super-senses will help them unlock the mystery surrounding an artifact recovered from an ancient Viking settlement. The object--a coin strung on a leather cord, discovered in modern-day Newfoundland--gives off strange energy traces that the museum's scientists have been unable to identify, and they're hoping that Superman's enhanced senses and experience with advanced science and eldritch energies can shed some light on the subject. The Man of Steel sees both chroniton particles and magical energies swirling about the coin, but when he touches it, the energy starts swirling around him instead! When he looks up again, he's been transported into the middle of a battle between the forces of time-traveling despot Per Degaton and a Viking colony, led by Prince Jon and Thor's half-Sioux son, Wakiya-Cante, for the fate of a captured Valkyrie!
