Grindle-Morian Civil War

The Grindle-Morian Civil War is an event mentioned in. It is briefly spoken of after Link, Princess Zelda, and Charles of Moria are ambushed by a Darknut in the woods. Deciding to use his sword as means of fighting the Darknut, Charles tells Zelda to relax, mentioning that his great granfather used that sword during the Grindle-Morian Civil War.

Given the fact that it is later discovered that Charles is actually Ganon in disguise, it is possible that the Grindle-Morian Civil War never happened. This can be assumed due to Princess Zelda saying earlier in the book that she had never heard of the land of Moria, and was probably made up by Ganon to effectively cover up his disguise as Charles.
