Deep beneath the underground city of Solasterra, some paths do not behave the way paths should. Lights fade where no one is supposed to walk. Doors appear where no doors were supposed to exist. And some routes do not always lead back the same way. This small private record was written quietly by two children who noticed what others did not. Thessa and Iren were not given maps. They were not told to keep records. They were not supposed to follow the deeper routes. They wrote what they saw anyway. Inside are incomplete notes, uncertain observations, and the first written report of something moving beneath Solasterra — something the tunnels themselves seem to remember. PENN: The First Report is an origin record from the world of Solasterra and the first discovered entry in the PENN Field Records. Further records remain sealed. This is not a typical fantasy story. It is presented as a recovered field record from a hidden underground civilization — a quiet, fragmentary account of children mapping forgotten tunnels and marking places that should not be found. Solasterra is a living world shaped by memory, secrecy, and unseen danger. PENN Field Record — Volume 0 is its first discovered document. R. A. Wadatz is an independent fantasy author and world-builder creating the Solasterra universe — a hidden underground civilization told through field records, origin stories, and discovered documents.
