There's only so much you can say about a product like this. It's essentially just a list of 100 location names with a little bit of elaborating detail suitable for a fantasy or sword and sorcery setting. The names are a good mix of semi-random gobbledigook (Ghenuhi, Spukara) and compounds of English words (Gatesteed, Marshflint) and all are pronounceable although some are easier than others. The location details are all thematically appropriate to the location name, so you get mines in mountains instead of shipwrecks, which tells me these lists are curated rather than just completely randomly generated. The overall feel of the locations is very old-school sword and sorcery.
There are several ways to use these tables, either in play or during adventure design. If you're starting with a completely blank slate, doing worldbuilding or adventure design with no existing setting in place, you can use them straight. Where has the evil Liche-King taken the kidnapped Prince? Why to the (roll) old abandoned Dwarven Vault in the Gatesteed Cliffs, of course.
If you're trying to flesh out an existing map or setting, where not every result on the table will be appropriate, you can deconstruct the location result and use bits as you need them. If you're looking to name a river, it becomes the Gatesteed River, a hill becomes Gatesteed Hill (or Gatesteed Rise, or Gatesteed Tor etc etc). Conversely you can just use the detail bit to inspire adventures in existing locations. What's special about the Ironwood hills? Why it's (roll) an abode of an exiled vampire count. Finally you can use the table result as a jumping off point for a free association naming. For example if I'm looking to name a river and get "5 Bleeding Forest of Valknad (abode of an exiled vampire count)" and none of those elements feel suitable, I can pick out a couple of key words, swap them for synonyms, mangle them around and end up with something like Redcastle Brook.
Like any random table product, this is best used as inspiration for a GM's creativity rather than a hard and fast roll=result approach. The names and details in this product are nice and evocative and lend themself to this sort of inspirational trickery. The Alien Biomes series has become an invaluable part of my Sci-Fi/space opera GM toolkit and the Fantasy Biomes series has the potential to do the same for my D&D game.
