As the two garden blocks were flying across different dimensions, they soon stopped near a huge castle. As soon as both blocks came to a stop, all of the occupants came out at the same time, then saw each other, and they all looked surprised...
Star: Nathaniel, Twilight, Ember... how did you get here?
Twilight: (nervously) Well... I might have wanted to show you and Dad that I could be a responsible person...
Nathaniel: And I said I would go with her if she was going to do this.
Marco: I will say, Nathaniel, that you are responsible for protecting your little sister.
Ember: I came along because I wanted to show my parents that I'm capable of going to other dimensions by myself.
Marco: (annoyed) So, you all decided to sneak onto a garden block without us seeing you?!
Star: (also annoyed) And also put yourselves in danger?! Ember, do your parents know where you are?
Ember: (guilty look) No, they don't. I just thought I would join Twilight and Nathaniel on this mission to prove myself to Mom and Dad.
Star and Marco sighed reluctantly, while Tom and Janna smiled in amusement. While the royal couple of Earth-Mewni knew more people were coming with them, they were a little happy to have some extra help.
Tom: Well, they're here anyway, so I guess we'll just have to bring them along with us.
Janna: (slyly) That's a wicked idea, honey.
But there were some rules for them...
Star: We need you kids to stay close to us, and use these walkie talkies to tell us if you see something suspicious, okay?
After the Queen of Mewni-Earth gave Twilight, Nathaniel, and Ember a walkie-talkie, a woman from behind everyone had spoken...
Woman: Star, Marco, and Janna?
Everyone had turned around to see the woman, whom Star, Marco, and Janna recognized almost instantly...
Star, Marco, and Janna: Sofia?!
Star and Janna squealed with glee, as they ran over and hugged Sofia, while Marco and Tom rolled their eyes...
Star: Sofia, it's been a while.
Sofia: (looks at everyone else) Who are these children and your three-eyed friend?
Star: These two are mine and Marco's children, Nathaniel and Twilight, and their friend, Ember.
Janna: And this three-eyed guy is my husband, Tom, and our two children, Raphael and Richard.
Tom: (bowed down to Sofia) Greetings, your majesty.
The five children waved hello. Sofia motioned for everyone to follow her inside the castle. They all walked upstairs to a room, where after Sofia had knocked on the door, a gray and black haired-man with a purple robe and a yellow bow tie holding a gray and black-haired baby with blue eyes, and wearing a pink nightgown, had opened the door to see who was there...
Sofia: Cedric! (she gives him a kiss) How is your potion for a new kind of medicine coming along?
Cedric: Well, it's coming along fine, sweetheart. I think I'm making a breakthrough.
Sofia: Everybody, this is my husband Cedric, who is a great sorcerer, and our baby daughter, Locasta.
Sofia: Cedric! (she gives him a kiss on the cheek) How is your new potion for medicine coming along?
Everyone introduced themselves to Cedric, and looked at his and Sofia's daughter, fawning over how cute she was.
Tom: I apologize for saying this, Sofia, but Cedric seems to be a older guy.
Janna: Yes, it's interesting. How did you get together with him?
Sofia: Well, after I graduated from Royal Prep, and also taking some time off from being a Protector, I spent time with Cedric in his workshop. After we hung out a few times, we started to fall in love. After a few months of dating, Cedric proposed to me with an emerald ring, and I was so overjoyed when I accepted his proposal! My friends and most of my family were excited about me getting married, but it took a while for my father to accept it, because I wasn't getting married to a royal prince. Eventually, though, he accepted our marriage, too.
Cedric: A few years later, Sofia gave birth to our daughter, and we became proud parents!
Sofia: We now live in Mystic Meadows, where I'm close to my job. We still visit Enchancia sometimes, especially when Cedric has an idea for a new potion. He just loves to show Locasta his old workshop, and enjoys using those potions for good. (laughs) Anyway, welcome to Enchancia! Did you come here to visit?
Everyone then told Sofia why they came to Enchancia, and how much trouble their worlds could be in...
Sofia: (shocked) You're saying that Vor escaped from her crystal?!
Star: Yes, and Mina Loveberry, our enemy, is also working with the most powerful sorceress you've ever defeated.
Marco: Someone had transported them to Adventure Bay. We don't know what they're planning over there. We thought you could come with us to this world and help us stop this from happening.
Janna: Especially since you're an expert Protector.
Tom: So, Sofia, would you help us save our worlds?
Sofia: (determined) I sure will, especially since Vor is now on the loose!
Ember: So, how do we take that team by surprise?
Nathaniel: We could find out what flaws they have in their plan.
Raphael: Yes, we need to be prepared for what's about to happen.
Star: We'll need to take a garden block to where the town of Adventure Bay is. Let's go!
With that Sofia, Cedric, Locasta, Ember, the two royal couples, and their kids then located where the garden block which would take them to Adventure Bay. They were on their way to help those citizens stop that evil alliance from turning the entire universe into a dark world...
