High Speech

In Mage: The Awakening, High Speech was the original language of Atlantis before the fall. All spells could be spoken through this form of speech, though the language is too fragmented to be used in everyday conversation. When mages use High Speech, they find it easier to cast their spells, while using Atlantean glyphs lengthens the duration of said-spells. However, sleepers cannot understand or even hear High Speech, the Lie forcing them to hear only static or some other abnormal noise, thereby increasing probability of paradox.

The Nature of the True Tongue
Some speculate the nature of High Speech to be not so much its own language, but rather the origin of all languages.
