Back on the last board, a very kind user helped me by finding an incredible list of languages. Between he and I, we might have actually found every language in 3.5 but three or maybe four.
I need all the languages so I can sort out a list of "usable" ones for the Fox and Tree martial discipline, which is uses Speak Language as its key skill. Even though Speak Language doesn't have ranks or a limit on how many you can know. I've had to make some fancy adjustments for that fact, and it has been fun, but...
It would be very helpful if folks could help me track down the sources of all these languages. I don't have all the books they were found in, and it would be nice if you kind users could lend a hand.
And here's the list:
