I'm new to the game, yeah, very new. I'm lucky enough to get into a house that can stand on its own. However I have seen something related to conquering cities. I had a glance at the world forum and spotted a player asking his same-nationality fellows from other in-game kingdoms helping him to capture a city for his in-game kingdom. Technically, asking help from several houses in several kingdoms to capture a city, so that a weak house can own a good city. Is it legit or flawed?
