Hi there, and thanks for letting us know about the broken links! We'll get right on that.

As for the question, yes, everyone texts and writes in Sumerian. For items brought in, they are now illegible; however those who are familiar with translating unknown languages or are perhaps code-breakers may be able to translate text, IDs, etc. Items such as grimores may or may not be exempt, as it will be taken on a case by case basis.

I hope this answered your question, and sorry for the wait!
