Corona was a survivor of the Pre-Expansion Era (Planck epoch) of the universe. It somehow learned to "echo" its consciousness using Ybakra radiation so that it could survive the expansion and cooling of the universe. This resulted in its consciousness existing in such objects that mimicked the conditions present in the early universe, such as stellar nurseries. It desired to return the universe to its previous state. (TOS novel: Corona)
