A number of distinct languages exist within the world, and will need to be created in some basic form.
Tiberian / Common Tongue
The common language for all of the now former Tiberian Empire member nations, spoken by many outside these nations as a common trade language. Essentially "English".
Zaradan / Magus Tongue
The archaic language of the Magi, taught only by Magi to their apprentices. This written/spoken language is closely intertwined with Zaradan Magic, and is the chosen format of all known written spells. Careful pronunciation and execution is required in order to correctly cast a spell.
The guttural speech of the Karian people, with a crude written form.
A musical form of speech, with flowing words.
A deep powerful speech, majestic, with an unusually artistic written form.
The native language of the Jagar race, utilizing throaty purrs and hisses.
The native language of the Elph race, deep and rumbling, with harsh and "angry" sounds to it.
