hmm a timeskip of 100 years would be at this place unreasonable then...i doubt that our Game would live more than 100 years and the question comes to the mind what happens then? From my point of view we can guess that the Manskinner with his newly aquired lands would crush the remaining Munros happily continuing to sell slaves, all the while modernizing his Jarldom and trying to to befriend the neighbouring nations, this means mainly Elbereth, his only trading partner from his point of view. Of course trading deals would also be struck with Vasir to keep them out of the way. The only remaining neighbouring Nation would be Brighthall, with which he tries to build up a friendly relationship. But as it is he refuses the Suulian Orthodoxy for the simple reason that he despises their fundamentalism and fanatism.
And we can all guess that sooner or later Suul and Brighthall join on some Holy Crusade to take care of Miring and Elbereth due to their beliefs. THe Manskinner as well as King Erik both know that in such a case they would need each other. All three combined (Elbereth,Weyland and Miring) would be more or less able to hold Brighthall and Suul off...at least i guess so. Anyway Brighthall alyways seemed to me as a nation which had some big enemy in the West, which allows them only limited troop support for the East. At least it seemed to me like it when i look at the Zimtar raids which weren't retaliated by more than 2 or 3 Brighthall regiments.
End of situation in i guess about 20 years would be:
An Alliance of Weyland,Elbereth and (possibly) Miring against a Suulian Crusade. And now in this moment our dear Game would reveal himself. The Jarl wouldn't propably mind what the slaves were used for and continue to trade.Game i guess would not overrun the Weylands at least not immediately, he needs them for Slaves apart from the fact that without them he would soon be facing the Suulian Crusaders. This leaves us with several possible endings to this crusade:
1a) Weyland allies with Game and together they form a 3 alliance putting Elbereth and Miring into a pretty shitty position, as Erik due to his hate towards Magic propably refuses to join the Dark magic and well teh Trubaldsomes do what they always did...kill each other. From there we can guess that ELbereth and Miring will be crushed due to the attacks from both sides.
1b) Weyland allies with Game and together they join Elbereth and Miring in throwing back the Suulian Crusade, crushing Suul in the process and forcing Brighthall to accept a Ceasefire. In the following years Elbereth will propably have massive religious unrest due to cyclists,Pagans and Orthodox people fighting each other. MEanwhile Game will stay a threat and sooner or later decide to destroy the Weylands and take over Elbereth followed by Brighthall.
2a) Elbereth, realizing the threat of Game joins together with Suul and Brighthall to stop Game and Weyland with uncertain outcome.
2b) Elbereth,the Weylands and the other nations join together to fight Game(and in this case propably win). After that the Crusade will propably continue ending up with Brighthall and Suul on the upper side as the Weyland is main Warzone in the War agaisnt Game.
and these are just the possibilieties i can think of in the moment...and theres the uncertainty with Game...what will happen in 60 or 70 years...what will happen to the Weylands if the Jarl succumbs to his poison? in my opinion to many variables to decide on...i say we play on from this point...
