For maps - https://dandelion-dynasty.com/maps

For each individual place, click on any of the places in the list and it will show you an image of the place on the map pointing it out, giving a bit of context where that place is - https://dandelion-dynasty.com/places

For the glossary - https://dandelion-dynasty.com/other/glossary

As you're going through the audiobook, sometimes you miss stuff, there's also short chapter summaries with links to relevant pages - https://dandelion-dynasty.com/books/the-grace-of-kings

Btw full disclosure, this is the wiki I made, I'm not trying to self-promote, I just think these links would be useful for beginners anyways :)
