"Barbarian" essentially means "doesn't speak Greek". Technically, almost all of the modern developed world would be classified as "barbarian".
"Indian" of course refers to Christopher Columbus (or Cristobol Colon) not believing the Ptolemeian (sp?) nautical maps of the day (which showed a world about 8000 miles in diameter, to within around 5% accuracy). and arbitrarily deciding (based on "wishful thinking", not factual evidence or research) that it had to be way smaller. When he sailed only about 2/3 as far as even he figured he needed to go to reach China, and unexpectedly bumped into land, it plainly wasn't China, so his assumption was that he OVERSHOT and reached India. That would have placed China right about next to Ireland. Oddly enough, the local residents didn't understand a word of Indian, and still couldn't tell them where China was even after the Westerners taught them how to speak both Indian and Chinese. ....and he wondered why people laughed at him.
Now, if the remaining Lilmothit were to have gone "underground" in the literal sense of the word, we could have yet another round of quests set in caverns and underground dungeons to seek them out.
