The Layolam is Misha's other world. The universe she created accidentally when she was in her late teens.

Although a peculiar concept, the Layolam features heavily in six of the novels and is mentioned in most of the others.

The Layolam is derived from Hebrew "L'Olam." Eternity.

Ish's other universe came to the attention of the world through her books, although it was clear that her "Layolam" was more than just imagination. When she first started visiting this universe she would return with flowers that were alien to this world and coins, as well as injuries. Her mother largely ignored this until Ish published her first book and it began to become clear that something strange was happening to her.

Unable to accept the idea that Ish truly was visiting another reality, her parents, assisted by Rick and Elijah Gwilym, attempted to have her committed to a mental hospital.

However, although by her mid-thirties, Ish's family were aware of her other worlds, it was not until one of the species indigenous to the Layolam attempted to (unsuccessfully) conquer the Earth that Ish became known to the British and American governments. It is this notoriety, as well as her own fear of herself and what she can do that helps to shape Ish's character over the course of the books.

The Layolam itself is a blanket term for a whole, thriving universe, connected by the abilities of Trans-Dimensional lifeforms (or Cross-Worldlings) presided over by an elected body of men and women known as the Olam Council. Although Ish herself is goddess of the Layolam, such responsibility frightens her and she does not guide her universe as perhaps she could.
