Lingones, the capital of Gaul, is nicknamed the "Capital of the World" (世界之都). There are at least 3 usages of this exact wording in CN and EN both. Very curious that Mon3tr uses this term to describe this phantom city, unless GAUL IS BACK BABY

伊万杰利斯塔十一世: 辉煌的“世界之都”毁于一夕,咆哮的装甲战舰嘶哑沉寂,所向披靡的高卢老近卫军化为焚火与硝烟。
Yvangelista XI: The 'Capital of the World' fell overnight. Armored battleships went silent, and the Old Vanguard of Gaul was reduced to ash.

"看到号称“世界之都”的林贡斯,将永远不会再出现于任何一张泰拉地图上。 "
"They see Lingones, the 'Capital of the World', doomed to never again appear on a map of Terra. "

Outcast: 当林贡斯被维多利亚和它的同盟一起彻底撕成碎片的时候,那座曾是世界之都的巨型城市彻底沦为炼狱,景象远比眼前惨上百倍。
Outcast: Lingones used to be a massive metropolis, many years ago. You could call it the capital of the world. But Victoria and its allies decided to burn it all down. One of man's greatest cities reduced to a raging inferno. It was a hundred times worse than this, believe you me.
