Language in the Apocalypse

There are hundreds of languages in the world, but in the post apocalypse, only a comparative handful really matter. Each region has a dominant language. In addition, there are a few commonly used languages of the Celestials and other otherworldly beings. Beyond that, there are a lot of languages in the world still, some clinging on in small communities of humans, some brought over by monsters.

Machine languages, such as those used for programming, still exist, but are very seldom used outside of Hades Towns, though even those make comparatively little use of them.

Regional Languages
By in large, the dominant language of each region was the language used most, or by the most dominant culture, in a given region prior to the apocalypse. There has been some drift since that time, mostly involving intermingling of languages and loanwords, but things are mostly stable language-wise.

America/British Isles/Australia- English

Europe- German

Asia- Japanese

Africa/The Middle East- Arabantu (a pidgin of Arab and Bantu that has arisen since the apocalypse)

South America- Portanish (a pidgin of Portuguese and Spanish that has arisen since the apocalypse)

Celestial Languages
Enochian, The Words of Creation, The Dark Speech

All Celestials speak the language of angels, Enochian. In addition, angels and demons have their own languages. Angels speak the Words of Creation and Demons speak the Dark Speech. These languages are more source code of the universe, but they can be used to communicate. When mortals use the Words of Creation or the Dark Speech for their magical purposes, it usually causes strain to their bodies in the form of nonlethal or ability damage.

The Words of Creation
The Words of Creation, when used to communicate, are somewhat akin to the concept of Newspeak. They are capable of conveying very negative ideas, such as enslavement, destruction, and brainwashing, but always as if these are positive things. When it would speak of such things in a light that is negative to the speaker, it tends to use very broad terminology that is closer to "corruption" or "godlessness." The Words of Creation can speak of giving oneself over to another's whims in a poetry comprised of more words than are found in a dictionary, but use only a few words for all kinds assaults upon the speaker--or the speaker's master. In the Words of Creation, a single word is used for both sin and falling to another.

The Words of Creation also have a potent magic. They can empower the music of a bard, augment conjuration magic or improve the crafting of magical and mundane, and be used to gain a modicum of control over another by speaking their true name. Celestials have the innate ability to use the Words of Creation in this way, but mortals must take the appropriate feat.

The Dark Speech
The Dark Speech is essentially the opposite of the Words of Creation. It communicates negative ideas incredibly thoroughly, with hundreds of thousands of words for different kinds of pain, torment, and infringement on the self. The positive ideas that the Dark Speech communicates best are self-centered. The Dark Speech communicates personal freedom in an accuracy that rivals its words for pain and torment, but has to construct unwieldy groups of words to talk about freedom for others.

Whereas the Words of Creation build, the Dark Speech (mostly) tears apart. It can cause dread in others and weaken objects, but its ability to empower magic is limited to evil spells. The one thing the Dark Speech can create is a hivemind that ties together large conglomerations of similar vermin or animals.
