This script was likely created long after its spoken form was standardized, as dragons had little to no need to write when compared to other races.
The Iokharic alphabet was equivalent to that of human languages, with the same number of characters for letters and numbers.
To give emphasis to important concepts, Iokharic employed a special character consisting of five (or six) lines radiating outwards, similar to a star or an asterisk (*), or the five heads of Tiamat. When this character was written, the word was spoken with both the first and last syllables stressed.
History
Elven scholars theorize Kobolds were the ones who created Lokharic, as it is widely believed the earliest Kobolds served Dragons, learning Dragon ways. The oldest historical records of kobold history began with paintings, then pictograms, and gradually developed into the Iokharic script.
