Regarding the fiber glass shattering in cold conditions, I think we'd find that to be in severe cold like in the minus's, anyhow with the foam wrapped about the fiber glass and the latex over it, it really is a nicely insulated piece of rod .
Then again given time available to work on the gear pool, the game will most likely end up in the coming summer or the one after, also depending on upcoming real life events.
I would suspect apart from the Gypsies traveling outside of the valley that Mordavia's valley would be made up of various sorts of people, after all it's not an easily accessable valley, so over larges amount of time people would have wandered in decided to settle and villages are formed, the isolation would also explain the strange things that exist in the valley, kind of like "The land time forgot", but more in the sense of outside world time is a lot slower there.
For those who don't know the year I've set this at is 284AD, mostly to fit in with the state of the Roman Empire at the time
"200-299 Recession and soaring inflation ruin the economy. Twenty-two emperors come and go. After 250: Increasing invasions of the Roman empire by Franks and Goths. Dacia is abandoned in 270 and the Danube becomes the empire’s northern border. Also increased conflict with the Parthians, and a Roman Emperor is captured."
Makes it a lot more chaotic for the Romans and ultimately for the Legion, also gives this Legion a reason to pursue a repelled Germanic invasion.
Note the year is one year short of the Roman Empire being divided by Diocletian.
Also on the Germanic side things went something like this
"180-300 The Goths, who perhaps originate in Scandinavia, migrate to the region north of the Black Sea. They dominate and rule the population there, while establishing ties with the Roman empire, and divide into Ostrogoths (East Goths, between the Don and Dneister Rivers) and Visigoths (West Goths, in the Ukraine)"
By what I gather the Germanic Tribes were good as Goths to begin with, just changed their names to suit.
The only problem I have with the game year is it was during one of the many persecutions of Christians, which destroys the Priest Role Playing role I had in mind for a Player, however we don't always have to stay 100% commited to history, 95% is usually enough.
Regards to players ancestors etc, I'll leave that up to them, however just be warned I will be giving out a base template of certain beliefs and morals a Roman Soldier would expect to posses in that time period, however how one fills out their characters history is completely up to them.
Both Players sides will get given a brief of history before the current year, and will be expected to know certain important events, especially those of the 13th Legions, loses and victories.
Also in planning is a day game campaign that lasts a few months, based around the destruction of Pompeii by the erupting Mount Vesuvius, these day games will help potential CHCH players understand how the events of 79AD relate to the fate of the 13th Legion 205 years later being trapped in Mordavia .
