I invented Nrocinu and Nrocirt when I was thirteen or fourteen years old, and they formed part of the setting for two books called The Kamarand and The Kamarand 2. The first of these was the story of Jenny, Peter and twins Leanne and Paul, who separately acquired three sibling unicorns. Kind, steady Kyalas went to live with Jenny, flighty Rinella with Peter and the twins shared supercilious Odyllicus.

These three unicorns, who had retractable horns, and so were able to masquerade as grey ponies, had come from their home world of Nrocinu as part of their obligation to serve their kamarands, or active service on Earth, which stemmed from a long-ago kindness done to a unicorn, Kamarand, by a human being. The fourth sibling, Zaius, was missing, and the main point of the story was the efforts of the children and their friends to get him back.

Nrocinu was the first world I ever invented, and its name is simply a backspelling on "unicorn".

The second book concerned the invasion of Nrocinu by militant tricorns from the nearby land of Nrocirt. These tricorns were, of course, unicorn-like beings with three horns instead of one. They and the unicorns had been rivals for centuries and now the minor skirmishes have escalated to the brink of war. The 4 unicorns know it's their duty to return home, and the children go with them.

Here they meet tricorns Tridena and Trijella, who accuse them of atrocities. More unicorns, including Orella and her lover Oristus, join the story, and eventually Jenny discovers a terrifying creature with red eyes and a hole in its head where a horn should be; it's a legendary nilcorn from the mythical world of Nroclin. The nilcorns are the real villains, and so tricorns, unicorns and human friends band together to end the war.
