Earth-12

Earth-12 is a reality in the multiverse.

History
Earth-12's history was identical to Earth-95's and real life until 1912, when The Titanic did not sink, as here it successfully received a warning of ice ahead and slowed down accordingly. However, that The Titanic doesn't sink reinforces the ill-informed idea that the ship is “unsinkable”, and it ends up sinking later during World War I due to hubristic direction from its captain. Though few civilians were on board at the time, neither they nor the ship’s crew survive.

Trivia
