Caspian is a place name turned first name, best known through the Caspian Sea. It feels romantic, literary, and expansive, which is much of its appeal.
The name gained modern visibility through literature, especially Prince Caspian in C S Lewis's Chronicles of Narnia. That helped shift it from a geographical label into a recognised baby-name choice.
