The worlds that need you most right now are the ones still being built. The campus and the Backwaters are newer ground, and they run on a simple promise: the players who show up early and build the community earn more from the world than the ones who arrive after the dust has settled.
What the newer worlds reward
Teaching a class on campus, running a scene in the bayou, welcoming a newcomer into either community, these are the acts that grow the newer worlds into places worth being. The world recognizes the effort with stronger boosts, because building a frontier is harder than walking into an established city, and harder work deserves a stronger answer. The more you put into the campus or the Backwaters now, the faster your own character grows while you do it.
Every world in this universe was built by the people who showed up when the ground was still raw. If you want to be one of those people for the next chapter, the newer worlds are where that starts.
