Wolfgang Hohlbein is a German author of science fiction, fantasy and horror fiction who lives near Neuss, North Rhine-Westphalia. His wife, Heike, is also a writer and often works with her husband. She often comes up with the story ideas and therefore is generally credited as co-author. Their daughter, Rebecca, is also a writer. Writing short stories since age 15, Hohlbein was first recognized as an author after sending in a manuscript he and his wife had written at a fantasy and science fiction writing contest in 1982. They won and their book, Märchenmond (English title: "Magic Moon"), was published by Ueberreuter Publishing, soon becoming a bestseller and winning several awards. It is one of their greatest successes till today. Many of his more than 200 books are translated and published in many European countries as well as in South Korea. Yet for many years none of his works had been translated into English. In 2006, Magic Moon was translated into English and published in the United States.

Timothy Stahl is an American-born author who spent much of his life in Germany, but now lives in Las Vegas. He started writing short stories in the 1980s, and later wrote for the Perry Rhodan and Maddrax pulp booklet series.
