Story
In Hadrian Rome, Lucius was a Roman architect whose designs often got rejected by builders. To cheer him up a friend of his invited him to relax at a thermae (public bath). Inside the bath Lucius was accidentally trapped in an underwater hole by suction; when he finally managed to emerge on the surface he found himself in a very different bath: in 20th century Japan.
