There are some thing which seems strange to me. And at least, as you won't change them, perhaps you can add some details... It's all based on timescale of the Great War. A war raged between 4 CY and 89 CY between Traxx Legion/Irenni League and Thullian Empire. Then the captital city felt. And then the Great War raged between 89 CY and 340 CY until the Empire surrender.
My problem is that I find that too long. In Europe, the war between France and England raged for more than one hundred years. But in fact it was a seccession of few years conflits with short periods of peace between them. The goal of England and France was not to destroy/conquier all the enemy's nation, just to conquier/recover a part of territory. And during Napoleon's campaigns, the french armies have conquiered all europe and have reached Moscow in only few years. What I want to say is that a full war cannot last that long without interruption.
BUT, it is still possible to detail some interractions between the wounded Empire and the Traxx Legion. Some periods of relative calm, where each side prepare its new weapons and swear to keep the peace. There could be some "cease fire" treaty which were not respected by one side or the other. There should be some period of time where the war slowly decreased because of internal conflict in the Traxx Legion or Irenni League. There could be some period with a turn of the tide of the war. Ok that's just few solutions... I just wanted to say that it should be better to explain WHY the war was so long.
In the same way, it's hard to understand how it is possible that the Empire can still fought for more 250 years while Traxx troops were able to reach their capital city. Was it only a guerilla (like in Afganistan/Irak nowaday)? Was the capital city recovered by Empire? Was this traxxian assault too hurry and unable to withstand Empire revenge? In my opinion something is missing here, and you should add some explainations on that.
And eventually, the Great War age begins in 89 CY and you say that it is called "Great War" because every nation was at war at this time. I think it could help if you describe some other conflict, like "The Nation X was involved in a war with Irenni League and was destroyed/conquiered in xxx CY"
In fact, as I'm writing these lines, I think you could do a whole page specifically on the Great War (more detailled than the in the history section). :D
Yes, the Great War is a complex period of Khoras history and really should get its own section. Probably more than just one page, but a series of pages.
I've always envisioned the Great War as a series of wars and political stand offs punctuated by major battles and periods of calm. And yes, some of it would be fragmented much like guerilla warfare. I think it's described as a "series of small wars" at least once on the site. I don't mean for it to be interpreted as 300+ years of continual warfare.
But you are right... it does need some detail and clarification. Perhaps that would be a good topic for a monthly spotlight this year. All about the Great War.
