From Sodor to Wherever

While the Griffins are on a family trip in Sodor, England, Brian and Stewie suddenly spot Bian Zoldark and Carter Pewterschimdt having a conversation in the same station. When the two men get inside the train Thomas, Brian and Stewie decide to follow them and ride on the train without getting caught, with Chris stowing away with them, stupidly thinking the truck of coal Thomas carries is a toilet. As the three continue to ride along the train, they come across a very unfamiliar railway which leads to an underground tunnel that keeps going down for several minutes until the descending slope stops and they see the light. When the train leaves the tunnel, Brian, Stewie and Chris are awestruck to find themselves into a new, completely different and magnificent city with massive sky-high towers, beautiful landscapes and wondrous locations.

Welcome to La Gias

When the three get off the train, they get caught by the city's guards. Carter is shocked to see them and pardons them since they're his family. They are welcomed to the Kingdom of Langran, the most prosperous kingdom in the underground world of La Gias. The Crown Prince Feilord Gran Birseia kindly greets the visitors. Afterwards, they are given a tour across the kingdom to witness some of its most prestigious sites, places and wonders.


Unfortunately, for the people of Langran, Alzarl was killed in a terrorist bombing in the Royal Palace. After his death, the Langranian government pinned the blame to the Shutedonias, a faction that the Kingdom of Langran has a long cold-war-like rivalry against.

A Looming Conspiracy

During their stay in the Kingdom, Brian and Stewie suspect that something is not right within the Langranian faction, concerning their feud against the Shutedonias and Carter and Bian's back-and-forth approaches with the Royal Family.

Carter's True Intentions

An enraged Brian asks the corrupt businessman why he abducted Monica and what his endgoal is. Carter revealed that he had Monica kidnapped not only to escalate the La Gias cold war into an all-out conflict, but also use her as a blackmail ploy to force the leaders of Langran to purchase weapons of mass destruction that he had kept in his Industries for a time, becoming a private supplier of weaponry to the Langranian military and keeping both the spoils of both Earth and La Gias to himself.

The Awakening of Volkruss

However, during all the commotion, Luozorl manages to complete the ritual and awakened the wicked Dark God of all La Gias, Sava Volkruss.
