Just let me know how this sounds.
The landlord Route.
-Buy Houses and asign 1-2 elfs to each (¿Lin and Jin's parents?)
-Rent houses, with elfs included as Staff and since they are your's and not your tenant's they are not to be harmed or face legal consecuences.
-More money => More houses =>More elfs => More money.
Create a gated comunity where your elfs are free to roam.
Then open a casino. Get even richer. Then buy a big ahh farm and put your elfs to work it for even more money to buy more elfs.
Then have a Baby with Autumn and Kali because you love them, but also, so you have political and financial support to buy even more land where your elfs can be free.
And when all the elfs are your slaves... none will be.
