Translated from an ancient Germanic dialect, The Mysteries Within is established as the oldest known and most obscure reference dedicated to the principles of inter-dimensional non-Euclidean geometry . It outlines the manipulation of harnessed eldritch energies through common reference points that intersect the curvature of inter-dimensional space. The basic and most practical use of such energies is the development of an inexhaustible power source based on “magical” principles. The memory of human history contains only the most fleeting and sporadic references to this extremely rare and powerful text. It was finally discovered among the collection of a quiet, reclusive scholar named Dr. Harrison Lovechild , and is donated along with the rest of his library to Miskatonic University in Arkham, Massachusetts , upon Lovechild’s mysterious disappearance and assumed death.
