The witches use a sustained spell to maintain a dome over the village. Outside, a glacier running down to the sea helps keep out unwanted visitors. The dome can be seen by the witches, but mundanes (non-magical) people only see more glacier. By all appearances, a very inhospitable place.
The witches don't keep to themselves entirely. Every Spring, they send a small cargo hauler to the northern shores of Norway. They trade various slightly magical charms and potions for more practical items like DVDs for their 52" flat screen TV. They also keep in contact with witches and the troll nation the rest of the time by albatross mail.
In BAD SPELLING, the other important area is purely mundane. The Sami tribe of Siberia are Kat's father's side of the family. She wants to find them and, with the help of Rune, the trolls, a six-pack of werewolves, and a few others, she makes it to the northern end of the Ural Mountains.
In MIDNIGHT OIL, Rune visits the real island of Novaya Zemlya. During the Cold War, the Soviets tested nuclear devices on the island. In my book, I use that real fact to explain why the island has mutant Nenets tribesmen: Radiation!
In SCOTCH BROOM, the siblings end up in the real Scotland, but in the other-dimensional Otherworld of Celtic legend. The Otherworld is sort of located in the Highlands. I say 'sort of' because it's not a place you can see (unless you're a magical being). Over the centuries, many fey, kelpies, unicorns, and other arcane creatures of the world have entered the Otherworld to live their lives in peace away from human influences.
The Otherworld creatures can come and go as they please, but it takes a lot of runic spelling to enter if you're not a permanent resident. Be especially careful if you do stumble into the Otherworld. You can visit, but if you decide to stay, then somebody already in the realm has to die. It's the epitome of a 'nice place to visit, but I wouldn't want to live there.'
