This book provides examples of:
 * Chekhov's Skill: Teresa is good at telling stories, Baz/Bors is an amateur drummer, Joshua is... just a bit kleptomaniac.
 * Doorstopper: While not as hefty as some other books, it still clocks in at a perfectly respectable 640 pages.
 * Dream Land: Umaya.
 * Did Mom Just Have Tea With Cthulhu??
 * Dub Name Change: Bors becomes Baz, Joshua Tak becomes Joshua Cope, Giphart becomes Gippart, and so on.
 * Britain Is Only London: and in the original Dutch book, The Netherlands are only Amsterdam
 * Half-Identical Twins
 * Reality Warper: somewhat justified - they're in Dream Land. Joshua can change things by looking at them. Teresa also qualifies - she can change things by telling stories. These example are not a Game Breaker because 1) these powers are limited: Joshua and Teresa can't do everything they want; 2) they're are initially unaware of their powers.
 * Time Master: Baz/Bors
 * Theme Twin Naming: Joshua and Jericho
 * The Storyteller: Teresa
 * Time Travel: but in Dream Land.
