You can read and write in poneglyphs. Scholars are close to the only people in the world that can do this, and are actively being hunted by the world government as a result. When you attempt to recall common information about an area you know the true name of, you automatically succeed any check to do so.
Additionally, you are well-versed in the lore of the world. If you do not know a specific piece of information when you try to recall it, you instead know where you can learn this information if it can be found in places such as libraries, scribes, or held secret by known sages. Your DM might rule that certain information is near or completely inaccessible, or that it can only be found in one specific place that is extraordinarily difficult to reach.
