Before we get into the story, I highly recommend that you read Todd Howard Destroys the Multiverse and World War Splatoon, because it contains spoilers from both books.
Callie and Marie hold eachother while going through the portal. The portal spits them out somewhere, and they crash into a tree. Carrie gets out of the car, and vomits because of motion sickness. Marie gets out of the car, and tries to get a lay of the land when she see's a building.
Marie speaks up and says, "We can find shelter over there!" She points to the building. Callie looks just in time to see a silo hatch open, and a missile launch from it. Marie thinks she can see a person on the missle. She see's the missle crash into a space ship, and explode into a nuclear explosion.
Marie and Callie recoil away from the bright light, and think its best to get out of the potential radiation zone, so they begin running to the building. They arrive to the building to find a man, sitting with his back on a old car. "Now who or what the hell are you?" The man said, clearly sounding like with no more fucks to give.
"Well, uh... my name is Callie and my cousin over there is Marie." Callie said, confused that he didn't know them, and that he is not a inkling. "Todd, Todd Howard, and what species are you, exactly?" Todd inquired. "Inkling." Marie responds.
Todd gets up, and smokes a cigar while saying, "Welp, sorry to break it to you but... this ain't your home world." Callie says to Marie to "Get the car." Todd stops and says, "A car you say?Why didn't you bring this up earlier?" Marie, after 10 minutes arrives with the car.
Todd looks at it, seeing the the left side of the engine sorta crushed in. "What happened here?" Todd asks. "Tree." Callie says. Todd hops in, and Marie starts up the car, and drive off into the night,
Five years later...
Todd is in a noose, ready to be hanged for his crimes against the town. Before they can pull the lever so his neck breaks, a masked woman on a horse pulls up with a LeMat revolver, and shoots the noose holding Todd, breaking it. The lawmen try to shoot her down, but since she has a quicker trigger finger, kills them both in a second.
She drags Todd to her horse, and puts him on there. She rides on out of there, while being chased by Lawmen. She gets shot in the left arm, causing her to drop her LeMat, and she grabs her rifle. She aims behind her, and shoots one of the lawmen straight between the eyes.
The lawman falls in the way of a horse, tripping the horse up. The lawmen are gone, and they turn left into the forest when they're far away enough. She gets off the horse, and cuts the rest of the rope off Todd. She takes off her mask to reveal it's Callie.
"Callie, why the hell are you here?!" Todd says, confused. "Getting you out of there." Callie responded. "Look, just stay hidden. Make it to Inkopolis, something's gone wrong." Callie says, before walking off, leaving Todd with the horse.
