The Fall of Magic was an event caused by The King of Adarlan. He used the one Wyrdkey he had and made three towers of obsidian across Erilea and casted a spell using his magic which would make all magic in Erilea disappear. One tower was built in Noll, one was build in Amaroth, and one was built in Rifthold.
Location[]
The Fall of Magic only occurred in Erilea. Which includes, Terrasen, Adarlan, Eyllwe, Melisande, Fenharrow, The Deserted Land, The Red Desert, the Frozen Wastes, and the Western Wastes. The Fall of Magic did NOT occur in Wendlyn, The Southern Continent, or anywhere else.
Heir of Fire[]
Chaol Westfall, Aedion Ashryver, Ren Allsbrook, and Murtaugh Allsbrook work to piece together what led to the Fall of Magic. They discovered that the "waves" spread from different locations in Erilea formed a triangle across the continent. The first line went right from Rifthold to the Frozen Wastes. The second went down from the Frozen Wastes to the edge of the Deserted Peninsula. The third line went from there back to Rifthold. A spell, they believed, had been the cause of it, and they thought that if one of the towers was destroyed then the spell would be broken. Chaol asked Dorian Havilliard to help him confirm this theory by performing a similar spell on a smaller scale using three candles and a bowl of water. They set up the candles in a triangle around the bowl. When Dorian lighted each candle using his magic, the water in the bowl turned to ice. When they knocked down one of the candles, the spell was broken and the ice melted.
Queen of Shadows[]
Chaol tells Aelin Galathynius that to break the spell she needs to destroy one of the towers, and Aelin makes a plan to use explosives to blow up the tower in Rifthold. Near the end of the book, Aedion, Rowan Whitethorn, and Lorcan Salvaterre work together to blow up the tower. After The Fall of Magic is reversed and magic has been returned to Erilea, The King of Adarlan reveals to Dorian and Aelin that he blocked magic to protect Dorian from the Valg.
