In the description, it says "he ordered a wall to be built that would separate the Pict tribes from the rest of England."

This should say Britain, not England - when Hadrian's Wall was being built there was no such place as England. It was a few hundred years later that England and the English language came into existence.

How/where do I ask for the description to be corrected?

That should be directed to Garphill Games.
