You weird rationalists up in Kanata... Down here in the Kingdom of Texia we still hold on to the religious traditions passed down to us by our Roman ancestors. Hell, we just had a beautiful weeklong Saturnalia season dedicated to thanking Saturn for all that he has given us in the past year.
You guys are in the minority down there, though. In fact, I've got relatives in Trinitaria in the Republic of Texia del Norte: They say even in South Texia, the Invictians are considered to be strange folk; most Texians stick to the basic secular stuff. In fact, perhaps you know this, but maybe not; the current Emperor of South Texia has actually discouraged hardcore religious festivals, as to not upset the primary Scottish/Teutonite/native Victorian northerners.
Even here in Kanata, we know of the Texian Civil War of 1944-47, and it's effects on the rest of the continent; Kanata may be a massive & powerful country, stretching from sea to sea, but even we could have been badly affected by the regional violence which could have followed the collapse. (Thank goodness it was contained, though)
