Your lore for roleswap, hand it over :gun:
Omg I'll talk I'll talk--
So I gotta first iterate that (per my typical fanlore) Xephos was sent on a mission to observe Earth for conquering but mysteriously vanished as he accidentally crash landed on Craftia. The resulting happenstance along with his abused childhood messed him up and he'd been looking for ways back to his homeworld ever since.
Honeydew saved Xephos from his wreckage by fighting off monsters, lighting the way, and carrying his damaged body to safety.
His homeworld, in the meantime, noticed he was missing and his father (the grand warlord of the whole planet) found out about Craftia and decided to offload disobedient soldiers there, one of which being Will, who was dumped off there in an attempt to erase his existence on their homeland, though he was tasked with gathering information about Craftia which their army leader intends to use to his advantage. Will doesn't know any of that, so he just focuses on building his career there instead. Also, before all that and before Xephos was sent on his mission, Will took part in a college exchange program with Earth, so he spent a good few years there secretly gathering data before transferring to his "new task" - getting left behind.
Parvis was sent from Earth to Craftia with a group of other humans as a part of a social experiment, and was told he was entering a simulated environment. He first ran into Xephos along the way, who helped him set up his Respawn system before being unloaded onto Will. Littlewood was the one to break it to Parv that everything was real.
...
So, for this roleswap, I guess this Xephos got to complete his initial task in the observation and preparation for the conquest of Earth. He's a bit less messed up and doesn't suffer from paranoia as much. I think he noticed Craftia, so after he completed his mission, he took charge in investigating the mysterious planet and intends on stripping it completely of resources. In the process of doing so, he provides a similar "solutions" service in order to maximize good relations with reliable businesses and as such, profits.
I guess he just finds Honeydew on his own, all alone. Honeydew wouldn't have been a hero or had any sense of heroism because Xephos wasn't there to make him realise his heroic traits. So he just falls into his own impulses instead, and picks up blood magic along the way because it'll make him stronger. He never forgets his desire to go to the moon, though.
Will on the other hand is the one who crash lands on Craftia during the attempt to send him to Earth. So, he never lands there and never integrates into earth society, so he acts a bit differently. More militarized and less familiar with outside socialization. However, instead of returning home, he wishes to try and complete his mission and does everything he can to get to earth.
Parvis finds Will first like he did with Xephos in my original lore, and because he's a human from Earth, Will willingly takes him under his wing. I'm not sure if Will would break it to him that he's not in a simulation, and he might use that to his advantage. Hell, parv might even get to him with that thinking, and maybe that starts his descent into madness. Parv becomes his lab assistant, getting experimented on and performing tests for Will.

This yoglabs is probably black instead of white, and this "solutions inc" is blue instead of red. Just cause it makes sense.
