Jonah was a whaler man at the turn of the century, and spent most of his life as crew of the Charles W. Morgan whaling ship.
In his twilight years he was diagnosed with schizophrenia and confined to the Saint Antoine Convent, an insane asylum even then.
He escaped by swimming along a dark saturated cave which led to a well in the property's garden.
He carried with him his demons, however, until death mercifully found him at Savannah Georgia at the ripe age of 72.
In the Shadowside he found himself once again a prisoner of Saint Antoine, until he struck a deal with "Uncle Thing", trading his inside knowledge of the Shadowside's location for a promise of freedom via Hierogamy.
He cashed his check with Markus "Prince" Crown.
