The Eldar language is used to write deep, arcane secrets not meant for weak eyes. It is an advanced form of Draconic and has been used to encode especially secret pieces of knowledge, spells that are too powerful for most or that risk causing irreparable harm.

The Eldar Syllabrary resembles the Draconic script, but differs in key parts, being an order of magnitude more complex. It allows for very precise descriptions of arcane diagrams and very elegant descriptions of spells, in the same way that mathematical and physics symbols can be used to describe equations.
