Why we think Falkir is a pupet state? Easy, because it seceded peacefully from Aurvandil, because make the same ridiculous diplomacy, and because are as arrogant as the Aurvandils... Oh, and because both are 'heathens'!
If we believe your words, Falkir is not a puppet state, but a disgraced, ignored puppet state.
BTW. Fissoa didn't attack Falkir, It was the Falkirians the ones to attack Fissoa, without any war declaration! Even in this, both are the same!
