After some discussions, we came to the conclusion that the war between IW and the Commonwealth would be too unbalanced if Mercs applied systematically for IW. Furthermore, Queen Tamra was short on captains willing to lead her armies to protect her lands, and therefore decided to hire our services for an undefined period of time. This means that from now on, any attack on Apostate property is an attack against her, and any attack against Tamra's property or subjects is an attack against my mercenary company.
Two other things should also be noted, the first one being that since Tamra's realm is neutral, her newly acquired soldiers (aka apostates) can apply for whatever, whoever they want as long as those they're fighting for do not go against Tamra's interests; and the second one being that the other leader of the Apostates, Latvian the Deserter, respectfully disagreed with this course of action, and decided to split to recreate his original faction.
