Soot Sap
For hundreds of years and multiple generations, the Soot Sap has been extremely important to every culture found on Aewyn.
You'd think Soot Sap is like any other sap found in trees, but that is not the case.
See this sap has some special properties, such as its dark colours and incredible durability of its colour when other materials are stained with it - it is these properties in particular that makes this material so important and sought for.
Soot sap is tapped from the Nila Tree which is nearly found in every corner of Aewyn in these years, but it started off less abundant and only found in regions surrounding the equator.

History
It is thought to have been used in foods and other things, including colouring of cloths, and that is how historians believe the idea of using it to write with came from. Iranians seem to have been the first to use the sap for writing, which is also why many very early documents have been found in prime condition around Irai.
The world looked a lot different when the sap was first put to use, but in later years when countries and cultures met each other and knowledge were traded.
Trading routes were established with the soot sap being one of the first materials to be traded around the world. This is when Nila Trees begins to show up in far-away countries.
Cultivation began and from this time onwards documents are found written with Soot sap in every country. Historians owe most of their knowledge about older days to the discovery of Soot sap, as it is the main reason for all the readable documents that still exist today.
