Adventures into the Unknown #70 (1956)

Roger Jones, a wealthy man who squandered his fortune in a reckless spree, finds himself adrift in the Sargasso Sea after a shipwreck, awakening aboard a centuries-old vessel surrounded by sunken ships. Confused and alone, he begins to suspect he's not the only living soul aboard when he experiences strange, gentle touches and fleeting footsteps—leading him to discover Anne Manners, a woman born and raised in the isolated, forgotten sea colony.

PFC Roger Carter, a paratrooper on a routine mission to blow up a bridge over the Marne, finds himself inexplicably guided through a series of life-threatening situations—knowing hidden caves, ancient ruins, and even the precise location of a hidden tunnel—despite having never been to Dufresne before. As his unit fights for survival against unseen Nazi forces, Carter’s uncanny intuition leads them to safety, leaving his comrades stunned and questioning how he could know things he shouldn’t.

Photographer Mike Conlan pushes deep into the Arctic wilderness, driven by rumors of a lost city hidden beyond the known world. After surviving a brutal blizzard and near-fatal injury, he stumbles upon a hidden civilization beneath a vast glass dome, where advanced technology and a peaceful society thrive in isolation.
