We would consider this blockade of us, your neighbour to be an act of war. Please clarify if this is your intent.
I'm sure you just have to be polite and ask permission to cross their borders instead of threatening war. Probably had something to do with occitan marching thousands of troops through their lands and when they were told they needed to ask permission Arrowaine basically told them to fuck off that he doesn't owe any explanation to anyone or anything.
Don't know why anyone that condescending and arrogant would be accepted as leader - oh wait hes French leading the French, I guess its normal.
I'm sure you would react the same way if occitan marched thousands of troops through your borders without asking permission - stand up for yourself as strong norsemen and close your borders to those who didn't get permission from you first, which is exactly what HOC is doing.
Our war with occitan is neither of your guys' war, but I know we would never just march large armies across someone else's territory without requesting permission politely, I would request the same politeness of occitan, but i don't expect much.
