My old homebrew existed within a spelljammer context (though most campaigns played there had no spelljammer elements at all as this was not common knowledge) and when running the Slavers line of modules, I had some of the freed slaves be from Toril and Oerth (the slavelords had a couple of spelljamming ships at their disposal), which meant re-patriating them was difficult. I also had their "common tongue" be different - so when the guy from Toril spoke it I used Spanish and for Oerth I used (my terrible) French.
