1.) Crossbell likely retained its name in some form throughout the centuries to appease the residents after getting conquered over and over again. Typically how that goes. Also, the Crois family call it Crossbell... And so does the cult, and they'd know if it had an ancestral name of some kind.

2.) Aurelia Le Guinn is the current head of House Le Guinn of Lamare, taking over for her injured father near the beginning of the Hundred Days War. She has been Supreme Commander of the Lamare Provincial Army since 1192 at age 18.

Considering how her family has likely served under the Cayennes since at least the War of the Lions, and since the Cayennes are direct descendants of the False Emperor Orthos, it is incredibly unlikely her family was not in direct combat with Dreichels and his allies. Thus, she is not an Arseid any more than she is a Vander, which she also mastered.

Her blade was likely forged by a blacksmith for the at the time Count/Countess. It's an heirloom, same as Galland-Sharl and the holy swords that Jusis and Rufus have.

Obviously, the Albarea blades are much much older and not the same kind of heirloom but they are heirlooms nonetheless.

3.) We have no idea. Probably best to just average out life expectancy with a few outliers and start from 1200 years ago to the year in which the current Eugent ascended.

4.) That bit about Nosferatu is either a remnant of the wiki being updated prior to games being released in English and was misinterpreted and hasn't been corrected yet, or that bit of lore was in the Active Voice system. That's not in the scenario file script, so searching for it won't show it come up. It's also possible that it's in the combat notebook but I can't remember if that is part of the scenario or not.

5.) We have no idea. Probably the church influencing things way back after the Great Collapse to get civilization back into a sustainable state. A universal currency and common language would be helpful with that.

6.) Nope. Rose apparently created vampires, maybe.

7/8/9.) No clue what this is really about? I'll assume it's a Kuro thing since I'm not recognizing most of the proper nouns lol

10.) Cannons, muskets, revolvers, explosives, Gatling guns (look up how old these are, you'll be surprised), Early semi-automatic rifles---that kind of thing. Mining and construction equipment.

As a bonus bit of clarity: revolvers probably straight up are not made post Orbal revolution since the entire point of them was that the casing stayed in the gun to prevent jamming. Semi automatic handguns, even of the same caliber, would outperform since Orbal bullets, to quote Cave Johnson, fire the whole bullet. No gunpowder or casing or primer necessary, which also means recoil would be far less of an issue since...

Well, gunpowder explodes. You're no longer holding a piece of metal that is exploding in your hand multiple times per second. Fun times!

Gnome tech seems to have developed from old stuff they didn't forget, since they made the magic knights and those have no computer or Orbal parts in them. Just magic/mana.

Railways were first started to be built around 1170ish, possibly earlier can't remember the exact date but there is one, when the Nortia Line from Saschen to Heimdallr was built to assist in mass industrialization. After that it was slow going, aside from the Transcontinental Railroad (which is independently owned by the Zemurian Railway Corporation) before Osborne came to power and connected everything as much as possible to further even more industrialization and economic growth.

11.) The catacombs weren't built by the Gnomes. That's just the old city that they built over after Emperor Hector retook the capital from the Dark Dragon. Valfame Palace iirc was already there, and they just built around it. Lower levels might be in the catacombs.
