I Thought I Traveled Across the Earth, but It Was Actually a Different World?

When I woke up, I found myself on a ship heading to the United States. At this time, in 1859, it was the time of the gold rush, and soon the American Civil War broke out.

There were still many secrets in this world. Wait... How did a civil war to free the slaves turn into a war between vampires and werewolves?
