"Try anything, and I'll slit you from one end to the other like a snake."

- Kumarcaah while pulling a knife on Jim Hawkins

The Feathered Serpent, Part One
After Jim Hawkins, Harry Hawkins, Steffanie Hawkins, and Shemnon escape an angry mob from the land of Melek, they meet Kumarcaah in a marketplace. Kumarcaah observes that Harry and Steffanie are in very good health and are ten and fourteen years old, respectively. He tries to talk Jim into selling them to him, but Shemnon is able to talk him out of it.

Kumarcaah and his Pochteca allies track the Hawkinses and Shemnon as they go to Zarahemla. While Jim, Harry, and Steffanie are camping out for the night, Kumarcaah captures them and takes them along with his supply train caravan. Later, the prophet Nephi buys Jim, Harry, and Steffanie out of slavery.

In Zarahemla, Nephi relays a message from God about Jesus visiting them and to go to a different city. Jim, Harry, Steffanie, and Shemnon, accompanied by Jenny, Joshua, and Rebecca Plimpton, join the citizens as they begin their exodus. As they are leaving the city, they are accosted by a mob of nonbelievers. During the confrontation, Kumarcaah steals both Harry and Steffanie and brings them to his Pochteca market. Jim figures out what happened and tracks down Kumarcaah. Jim holds a knife to Kumarcaah's throat and threatens him into freeing his children. Kumarcaah reluctantly complies, but swears to feed Jim's flesh to the vultures if they cross paths again.
