Hall of Secrets
From Zelda Wiki, the Zelda encyclopedia
The Hall of Secrets is the place inside both the male and female Maku Trees, where Link can find Farore, the Oracle of Secrets. While going through the linked version of either Oracle of Ages or Oracle of Seasons, Link can tell 'secrets' to Farore to get special items. These secrets are obtained in several different ways, but are only effective in the game opposite of the one they were found in.
