Once the characters have learned to speak Adamic fluently, the information will probably begin to spread throughout the Order, possibly

Magic in Other Languages
Hermetic magic is based in Latin, because that is the language of learning in Mythic Europe, and has been since before Bonisagus developed his theory of magic. Magi can certainly cast spells without speaking Latin, but they suffer a penalty to their casting totals, just as if they were not incorporating their voice at all. To integrate another language into their magic, they have to perform original research, experimenting in the lab. This process is based on the rules described in Houses of Hermes: True Lineages, page 26.
Like other means of adapting non-Hermetic magic into Magic Theory, the magus must begin with a project, perhaps inventing a spell using another language that he speaks fluently instead of Latin. He is seeking to achieve a Discovery on the Extraordinary Results chart, and each time he does so, he produces a spell that he may cast using the new language. He may then attempt to stabilize this discovery, and if he does he receives a breakthrough point for each magnitude of the invented spell. Completely integrating this new language into Hermetic magic is less work than a Minor Breakthrough, requiring only 15 breakthrough points to achieve, and unlike other forms of original research, the magus does not gain Warping Points from this procedure.
Adapting a language to Magic Theory is not that onerous, and it is unlikely that the result will be considered a true "breakthrough" by other researchers in the Order of Hermes. Perhaps it has been done before, and exotic magi in lands further east have already converted their spells into Greek or Arabic, even using this language to teach their apprentices magic. Once this process has been completed, a character with the Living Language Ability at a score of 4 or more and Artes Liberales–based knowledge of the associated alphabet can learn the newly translated spell from a Lab Text, and from then on may invent his own spells in that language.
attracting the attention of scholars in more academic circles. Given that it is supposedly the first language of man, and presumably the language of God, representatives of the Christian Church, Judaism, Islam, and other faiths may also take an interest, perhaps declaring that it is a holy language, sacred and not to be profaned by wizards and magicians for use with their heathen rites. This could lead to great conflict within and without the Order.
As more and more magi learn the language, another idea that is likely to surface is the suggestion that Hermetic magic incorporate Adamic instead of Latin, for magic is so much more powerful when cast using the words of the first language. It is unlikely that Adamic could ever replace Latin completely, since all the greatest books of the day are written in Latin, as are all the authoritative tomes of their Hermetic predecessors, but in time it could become a sort of secret sign among magi, used among their own to help them hide their Arts within the populace.
Because of the incredible Penetration advantages that Adamic gives magi, widespread knowledge could lead to the downfall of the Order, since it negates the value of the Parma Magica as an equalizer. Then again, it could also ensure that Hermetic magic achieves supremacy over all other forms of magic, since magi would have both superior resistance and unstoppable strength. Ultimately, it is a discovery that would transform the way magic is used, and how magi are perceived by all other supernatural beings.
