Hi listeners, it's Vanessa. Before we get into today's episode, I want to tell you about another show I think you'll love.

Hidden History with Dr. Harini Bot. Every Monday, Dr. Bot goes where history gets mysterious.

Vanished civilizations, doomsday prophecies, paranormal phenomena, and events that science still can't fully explain.

Hidden History drops every Monday. Follow now on Apple Podcasts, Spotify, or wherever you listen, so you never miss a mystery.
