Eth'ral'khh is a logographic writing system composed of elaborate glyphs, mostly ideograms, that has been in use for centuries. Examples of the writing may be found embossed into Dragon Priest gear, or painted on the palace walls in Ratha. It is commonly described as sinuous or serpentine.
Due to the use of non-standard characters, it is impossible to represent Eth'ral'khh in the game engine itself. As of yet, no art has been produced by the game developers to represent the writing form either.
