The Story of Shellback & Neptune

For centuries, sailors have whispered of an ancient rite that separates the true seafarers from the untested. It is said that beyond the horizon, where the sun blazes on endless waters, lies the domain of Neptunus Rex, the mighty god of the sea. And to cross into his realm, one must earn his favor.
When a sailor embarks on their first journey across the equator, they are but a mere Pollywog, unproven and unworthy in Neptune’s eyes. But Neptune is not without mercy. He sends forth his loyal subjects—the Shellbacks, seasoned mariners who have braved the crossing before—to oversee the sacred initiation.
Dressed in regal splendor, Neptune himself is often portrayed by a veteran Shellback, presiding over the grand Line-Crossing Ceremony. This is no ordinary test. Pollywogs must endure trials of wit, endurance, and good humor, proving their worth to the court of the deep. Only those who pass with spirit and resolve may be granted the title of Trusty Shellback, forever welcomed into Neptune’s ranks.
To become a Shellback is to join an elite brotherhood of sailors, bound by tradition and the shared experience of crossing into Neptune’s kingdom. It is a badge of honor, a mark of respect, and a story told in the glow of lanterns on the rolling seas.
So, when next you sail across that fabled line, know this: Neptune watches. And if you are found worthy, the Shellbacks will welcome you into their ranks, forever a sailor of the deep.
