This is Part 4 of a Star Wars fanfiction I began writing 6 months ago. The order you read it in is very important. Start from the beginning for the best experience and to avoid spoilers.

Obi-Wan Kenobi bought passage from a scumbag with a confusing name. Luke couldn't discern whether Han's name was pronounced /hɑːn/ or /hæn/? Fortunately this story is in prose, not film, and the pronunciation of Han's name is not plot relevant, so I can just write "Han" and leave the choice of pronunciation up to you. Whatever pronunciation you pick, they emerged from hyperspace in the Alderaan system. Han briefed his passengers for their upcoming landing.

"Thank you for flying with us. We have received clearance to land and have begun our descent onto Alderaan. Please do not leave any contraband on this ship. Unless it's valuable. Then by all means leave it here, but let me know where it is," said Han.

"Grawr," said Chewbacca.

"You're right," Luke sighed, "I guess deep down I wish I lived in an exciting isekai universe full epic destinies, sci-fi technology, and princesses in need of rescue. Instead, here I am in the real world, 19-year-old Luke Skywalker, riding a YT-1300 Corellian light freighter to Alderaan."

"Grawr," said Chewbacca.

"You know," said Han, "I always assumed Alderaan was a temperate planet. I didn't realize it was a megastructure like Centerpoint Station."

That got their attention. "Alderaan is a temperate planet," said Obi-Wan.

The word "Alderaan" can refer to the star "Alderaan", the planet "Alderaan", and the star system "Alderaan". If you want to be pedantic, the planet Alderaan ought to be referred to as "Alderaan I". (In this way, Earth can be referred to as "Sol III".) But everyone just called it "Alderaan".

When Chewbacca entered "Alderaan I" into the navcomputer, that told the navcomputer to bring the Falcon to the first planet in the "Alderaan" system. A planet is a massive spherical object that has cleared its orbit of competing debris. The navcomputer defines to "Alderaan I" as the big massive object orbiting Alderaan.

Thus, the Milennium Falcon emerged from hyperspace not around Leia's home planet of Alderaan I (which no longer existed) but instead within kilometers of the Life Star.

Our four heroes looked at the Life Star through the cockpit window.

"You're telling me this isn't Alderaan?" said Han.

"Nope," said Obi-Wan, "Didn't you think to ask why we ...
