Their battle for ultimate Sith power led to their demise, as both succumbed to the fumes emanating from the Pits of Paxxis.
Luke Skywalker posited that this legend was based on actual events that transpired around 3400 BBY.
Skywalker acquired an image portraying this duel at some point. He added annotations to it, along with his copies of The Jedi Path and the Book of Sith, after the Emperor's demise in 11 ABY.
