This dimension is mentioned in the first novel. It is where Harrod, Adan's father, and his friend Macher, seek out evidence that the dimension was the precursor to Babylonian civilization with a similar cuneiform script and religious figures.
This dimension is well known for its unpredictable hounds and severe climate changes. Adan and Mara were chased by Giffordian hounds when Mara lost her digipad, hence, her notes of the entire adventure. What we do know is the mission to Gifford was the last time Adan, Mara, and Harrod worked together.
This is an subterranean dimension that is very peace loving though wary of strangers. It places a high value on educating young boys and girls who are interested in the fine art and craft of carving carrumite, which is an indigenous mineral used for architecture and day to day implements. Students are also trained as "tyers"--individuals who can translate the ongoing messages of "lumes" , which are tiny beads of light that continuously traverse the dimension cataloging conversations and actions. The tyers create tyes that visually record these actions, creating an archive. The first novel is set in this dimension, in which Adan and Mara aid Macher in saving the dim from a madman from the Uri dimension.
Since the list of known dimensions would fill a room, this site will continue to describe the most relevant ones for Adan and Mara's adventures.
