Yes you may, this will include all of the siblings.
Summary: after Venus's portal device malfunctions, the siblings end up in a strange dimension, and it's hard to believe it's real.
"Can you all shut up so I can focus!" Venus said as she tried to focus on typing in the correct coordinates, but with her siblings arguing, she messes up and a portal opens up, and the siblings are pulled into screaming. "Venus, what happened!?" Neptune yells as they travel through the portal. "I don't know!" Venus admitted, all while Pluto was screaming, Juni was having a panic attack, and Saturn was silent.
When they landed in the new dimension, they noticed that something was off, immediately. "Where are we? this looks like father's ship" Pluto asked, grabbing Saturn protectivly, while Juni looked closer at pictures. "But they have family pictures." Juni said, causing the other siblings to have a look as well. "Oh, my kids, isn't this a nice suprise" came a very familiar voice, but more happy sounding.
The siblings froze and then slowly turned to look at the other version of their dad in shock. "Why do you look suprised, my children?" The other grand Celestial asked, and Neptune spoke up. "Because we aren't from here, we come a different dimension." Neptune explains, hoping it'll get through to the nice grand Celestial, who's eyes widen with suprised. "So your my kids from another dimension? Well, you all still look fabulous, but tell me, what am I like in your dimension?" The nice grand Celestial asks, his face showing a curious expression.
The kids look at each other before sharing some stories. "Well, our grand Celestial abused me." Said Neptune, shocking the nice grand Celestial. "He turned me into a moon fallen and sent Pluto to kill me." Said Saturn, and the nice grand Celestial got a little angry at that. "I don't wanna explain mine but let's say it wasn't nice." Said Venus, the nice grand Celestial didn't pry for a explanation, even when Juni didn't want to say as well. "Abandoned me on a planet to fend for myself then tried to force me to kill Saturn." Pluto said, and the nice grand Celestial got even more angry.
The siblings were worried about how the nice grand Celestial would react. "This other me sounds like a real di-" before he could finish, Juni cut him off. "Language!" Juni shouted, causing the nice grand Celestial to freeze and look at her confused. "Apologies, it's a reflex, you see, we all work in Saturn's husband's daycare, and it's what we say to the children when they swear." Juni explains, getting a look of understanding. "Ah i see now, so Saturn's husband's is still Eclipse, yet instead of just her and him, it's all of you." The nice grand Celestial said softly.
The siblings nod while Venus tries fixing her portable device. "Now, I know I'm not your actually father, but is there anything I can do for you?" Asked the nice grand Celestial, and Venus looks up at him. "Yeah, I need help with my device, fath- uhh" Venus cuts herself as she realize what she's going to say, so do the others and they sigh, instincts were strong. "You can call me Father if you guys wish, or you guys can call me just Celestial. " Said Celestial, which got a smile from the group. "Celestial, I need help fixing my device, so I can get us home." Said Venus softly, and Celestial smiles. "Give me everyone's device, I would like to give you guys my number." Celestial says, a soft smile on his face.
After a while of getting Venus's device fixed, getting Celestial's number, and talking, the group got ready to leave, but before they did, Celestial spoke up. "Your all welcomed here anytime you guys like, as much as your my children from another dimension, your still my kids, and I'll treat you as such." Said Celestial, and the siblings froze, a little surprised by what he said, but Pluto soon ran to hug him, then Juni, Venus, Saturn, and lastly Neptune.
They hugged him for awhile before saying there goodbyes and leave, but it was to say, they would be going back to visit every once in awhile, they even saved his content number under 'Celestial/ better dad' in their devices.
