chunk: He next has a stay in the curious hidden kingdom of Twi. It is a land of perpetual twilight, hence its name. Everything is doubled in Twi, and everyone is a twin. The people even lack a word for "one." The local rulers, the High Ki of Twi (twins like everyone else), are considering the fate of the intruding Marvel, when he places a spell on the twins, dividing them from their united and shared mind into two separate consciousnesses. The results are chaotic, and Marvel has to remedy the mess by re-uniting the twins.
  Marvel next exposes the pretended magician Kwytoffle (a fraud, like the more famous Wizard of Oz). He meets his sternest test when he confronts the Red Rogue of Dawna; even then, however, his native fairy abilities enable him to emerge victorious. By the end of his mortal year, Marvel has pacified the formerly troublesome inhabitants; the Island of Yew has become civilized.
