When Payoang began altering the main Dothraki website to also handle Valyrian, he changed the title to be 'Languages of Westeros'. I think everyone here knows that this is not exactly correct, as Valyrian is little-spoken in Westeros, and Dothraki not at all. So, what would you have for a new title? Here are two I propose:
The languages of Ice and Fire
The Tongues of Ice and Fire
Do you have a better idea?
