Gallia can own Cortez without it impacting the starting of new players, if anything it would expose them directly to the storyline and raise a lot of questions that would prompt exploration and learning. Penn at the moment acts like a bubble, isolating newcomers to a daycare system that's away from any new developments and the day-to-day interactions of our community.
Cortez would do away with that by throwing new players directly into the story and offering several options to explore, plus as the main trade route between Liberty and Bretonia they would also have the potential to meet a lot of veteran players, both lawful and unlawful, due to its position beyond House borders. It would however need the various factions to get up off their backsides and actively help out new players with their questions, the primary reason why the Angels were disbanded.
