Really hope you don't mean me. [A joke...but give them a moment before two items appear in their hands. A red crayon, and a piece of paper. Sol begins to draw as they explain.]

So this dot is the core. This is where we are. Kinda like a home world...as the core starts to develop and grow, it starts to branch out and make contact with other worlds. [Drawing, Sol draws lines and circles to represent other worlds.] As the universe continues to explain, all worlds find themselves somehow attached to this core. The core is reborn every now and then to start growing the universe around it. If something's affecting the core...then it affects all of the worlds around it. See?
