This song was sung by Calder to place a curse on the entire world of magic oceans, with the intention of preventing any possible rival from discovering the magic master key before he does.

Lyrics from Potion Voyages Book 1: Castle & Conceit by Jeremy Dwyer

The Treacherous Trail to the Magic Master Key

These songs are magic spells using the original lyrics from my books.

My name is Jeremy Dwyer and I write the “Potion Voyages” series of adventure novels about a world of magic oceans. 

The most powerful magic is music and there are 106 songs, composed and performed by multiple musicians. 

The songs tame tempests, build cities, heal sickness, fight battles, summon storms, discover secrets, tear down castles, and travel to distant dimensions.
