Druidic

Commonly known as the language used by druids in the Councils of Briar Glen, Druidic is a much older language than those who speak it. It is known by archivists as the written form of the sways, creaks and whines of the Dreaming Oak trees; interpreted through dreams and symbols druids often attune to. To the naked eye, this language seems to contain scratches and symbols- to translate would be similar to interpreting a psychological inkblot. To the fluent, these 'inkblots' reveal the surface thoughts of the writer. To a master, they can convey whole sequences of thought, making the language terrifyingly efficient.
  Primordial is a language in a similar style to Druidic, however it is conveyed as a spoken form of symbolism.
