why not take a classic RPG approach with it and have the languages of the races, so we have kran, enki, ylian, xacha, stonebreaker, hammerwielder, diablo, ynwnn(i'm usuming this would be a cross-language between the 2 races which make up a ynwnn), demorian, nolthrir, klyros. and then have languages for alignments, stick with the basics of neutral, lawful and chaotic i would imagine. that gives the option to learn many languages with which to talk to other characters, and would also make RPing in hydlaa more fun as it would feel like a multicultural city when you read the chat box.
