Royal Brush of Truth

This brush has double divine power. First it is one of the most important symbols of statehood and of the current ruler and second, its bristles are made out of special golden threads that are according to the myth the manifestation of the heavenly power of gods, that is able to affect the entire universe and change reality at will. The magical properties of this brush might seem miniscule but in fact are quite useful. Whatever is written by this brush cannot be altered in any way, unless you burn the entire message. And then no matter whether you can read or not, and no matter your mother tongue, whoever sees the message automatically understands what the writer inteded by it without any room for error. Whatever is writen is the truth and the readers will know it in their heart to be it so.
Only the current king can use the royal brush. It is mostly used to write edicts and other important correspondence. Any royal message is also stamped with the seal of the current ruler as it was for many centuries before. It is the only known artifact that contains golden thread and manifests true magical properties. Some of the monarch also wrote journals and poetry with it and one king also used it as a painting brush for some of the landscapes that are displayed in the chambers of ministers. But whatever the author wanted to convey to the onlookers, they are always able to feel and understand it fully.
Caligraphy is the second most important artisan endeaver right after embroidery and it is considered to be another staple of the Inzu culture. Many people comission pens that have gold or bright yellow bristles to show the world that they intend to speak truth and nothing but truth.
