King Hieronimes was a King-Emperor of Kasagrad in the Time of the Tombs before the 4th century BC. He entered into a political struggle with his chief engineer, Rablev, who tried to usurp him before Hieronimes sealed him in what would become known as the Lost Tomb of Rablev.
Afterwards, Hieronimes wiped Rablev from the histories with the sole record of Rablev's crimes being within the tomb. His propaganda said that the gods had grown angry with Rablev and poisoned the land so that nothing would grow. (PROSE: Professor Bernice Summerfield and the Doomsday Manuscript)
