'Ancient One's Tongue'

Like all Folk, the 'Ancient Ones' had at least one language, possibly several. However after the world's magic levels crashed much knowledge of the language has been lost, as did much of the 'Ancient One's' knowledge and culture. As the ages passed, bits and pieces of the language has been rediscovered from recovered books, tablets, scrolls, and carvings. Most of this rediscovered knowledge has been scattered amongst the different folk and organizations.
Most of the language has only survived in written form, but some 'recordings' from when the 'Ancient One's' civilization was at it's peak has giving scholars a glimpse of how their language sounded.
It is also believed that some Gods may have existed during the Age of the 'Ancient One's', and as a result may know how to speak the language, but so far those suspected of having this knowledge has not been inclined to share it with scholars. (One scholar insists that he once heard a cloaked figure grumble something in the language, but when confronted, vanished into the crowd).
Recently there have been efforts to gather all knowledge of the 'Ancient Ones' under one roof, including the language, in order to both better protect it from 'The Descendents', who want to use the knowledge for their own gain, and to better study it. Understanding of the 'Ancient One's' language has greatly expanded the last few years, to the point where scholars were able to decipher parts of the ancient text and learn new spells.
Some have become frightened of what has been learned after deciphering some of the ancient texts, and there has been demands of halting research and sealing away what has been learned. The recent theft of deciphered scrolls detailing how to create Chimeras, by 'The Descendants' have only confirmed these fears.
