Well, starting small, doesn't mean we will stay small, once our work starts to pay off, and people start buying into it, we can ramp it up quickly. We do have a lot of backing after all.
While I do want to liberate as many as possible, we only have one reasonable way to do that right now, buy them ourselves. Unless we want to send them to the Desert or High elves, they would just end up back in the system again. Every slave Nia/Sui saves, goes right back into the system, to find a new master, hoping that they get one that is nicer than the last. She doesn't really 'free' anyone. Most of the ones she saves are from illegal slave owners and really abusive assholes that are breaking the law, she doesn't actually free them.
Cyber campaign, radio, TV, movies, and any other way to spread rumors and 'news'.
Just think about it... (off the top of my head...)
Jia and Grace - a show we can start making once we marry Jia, and it can show the two of them living together, and Jia can start to show that she is not useless without a human, like the campaigns they have going now, but she is the one who is always helping the bumbling Grace out of her weekly jams...
Elfville - a story about an elf who was abandoned and found by a human couple who raised her as their own, but she had to hide her identity, or the authorities would take her away (this could also work with a half elf, who had their ears clipped... maybe even Maria). Not only do they get to see her struggles with trying to hide, but she could secretly go around saving people (maybe using her 'elf magic'). lol Could be like a magical girl anime.
The Greatest Sylvanian Hero - A human who works for the government, maybe a parody of Cornwall, and his slave are out in the middle of nowhere one day, when suddenly a spaceship comes down, and gives them a super suit. The human, being a dick, makes the elf try on the suit first, in case it is dangerous, and it bonds to them, so only they can use it from them on. The human then thinks he can use the elf to stop crimes, which he says includes saving elves that are being abused, so the slave agrees, even after learning they are super strong, fast, can fly, and all that in the suit, but it's hard to control (hilarity ensues). So, the human tries to get them to enforce their laws, but the elf starts to get more and more bold, and less willing to take orders as the story goes, all the while, they are helping people, while the human continues to be a bit of a jackass, showing the elf as the hero, who ignores orders when it means helping someone.
Could do like a funny soap opera parody, like Soap, where they have an elf butler, who is always fixing all of the dumb family's mistakes.
Could have a post apocalypse story, where the humans and the elves went to war, and almost everyone died. At this point, only a few people still care if you are human or elf, some old hatreds stay, but most people are just trying to survive, one day at a time. Mad Mia! The leather clad elf, with a bad attitude and a heart of gold.
An Archie Bunker parody, where the dad is a bigot, the mom is nice but conservative, and the teen-adult child and their boy/girl-friend are both abolitionists. This one could have Ashley's dad as the inspiration for the main character.
Luu Pin - A story of two elves (Luu and Pin) who are master cat burglars, and do some robin hood shit, go around helping orphans, and other poor kids.
Space Trek Wars - Taking place far, far in the future, a long, long ways away, elves, humans, and aliens, working together in their federation, battling the evil empire... bla bla bla...
Starving Games - Elves, forced to fight for food, this is the story of one 'young' elf, trying to feed her sick mother, or whatever.
Similar Strokes - An elf slave dies, and her master 'adopts' her two children. The two kids could be based on Lin and Jin, "What'chu talkin' about, Jinny?!?!?"
Maybe 'The Elf Maid's Tale' - Another dystopian future, where most male elves are sent out to work, while all fertile females are kept pregnant at almost all times, as that is their only use, to make more elves and half elves. This story revolves around one elf maid, who learns that she is baron, and how much worse her life becomes once the word gets out. After she gets pushed around enough, she starts a revolution or some shit, or maybe it doesn't have a happy ending. That could also work to make people think, maybe she dies in the end, crushed by the system.
Ms. Android - An android ends up replacing a teacher at a school, originally she was just supposed to be a substitute teacher, but she does such a good job, and the kids like her so much, they keep her on full time.
The Elf-Files - Two government agents investigate strange cases, one of them always convinced that it is 'elf magic' that caused it, but in the end, it is always something mundane, and the elves were just a scapegoat.
The Toymaker - Use the web comic for yet another dystopian story.
Elf Park - A cartoon about 4 elf children, just being kids.
Mac, The Bounty Hunter - About a space bounty hunter, flying around in their armor, having fun... But, after a while, they take off the helmet, and there is an elf under there.
Need I go on? XD
The gallery if far from complete, it's better to play the game.
