If you like creating your own game worlds, but struggle sometimes to come up with names for places that sound real but aren't, this is for you.
It's just a list of an hundred names, but ones that sound like they might be found on a map somewhere... so why should that not be YOUR map? Some work better than others - Flotsam, for example, is a real word and you probably don't want your island to sound like it fell off a ship and floated away. And Thule has been used as a legendary place here on earth already, so unless you want the associated baggage of the real-world Thule legends, it may be best to avoid it.
Storn, however, is a good one. If it's not a real island already, it ought to be! Locuta or Lixus, Savoya or Sargill, Uffa... these sound like real places and soon, perhaps, they will feature in your alternate reality, places that will become real to you and your players as you create the stories of their characters' exploits there.
