My name is Toshiko Aeki, I'm male, and I am from Murdville. I am one of the few residents of my hood in the science career and we have been researching the new dimension via a website called Snooty Sims. It has almost everything that has been confirmed about our new dimension.
I and my alien daughter Haruka wish to go there ourselves when the time comes, but our Spokes Sim says that there are already 10 families from TS3 already who plan to live in the new Murdville, so only a handful of us can travel to the new dimension. The Spokes Sim says that there a plans for a "lottery" to decide who will go to the new dimension, but that's all we know for now.
