Sagefruit, a fictional plant in the How to Train Your Dragon Franchise, is a bright yellow to orange in color, fading into green at the stem end. While it is relatively rounded, this fruit tapers towards one end and does not appear to have a pedicel or calyx. It rather resembles a pear. The plant the fruit originates from is not seen in the Franchise.
Sagefruit is used exclusively by the Defenders of the Wing as a calming agent for dragons. It relaxes them without altering behaviors. For example, despite eating Sagefruit, Toothless and Stormfly still jumped to their Riders' aide when needed.
In the episode, "Defenders of the Wing, Part 1", the Dragon Riders are captured by the Defenders of the Wing Tribe on Caldera Cay. While still unconscious, their dragons were fed sagefruit by the hooded defenders. Later on, when Hiccup was sent into the pit of Speed Stingers, Toothless overcame the effects and rushed in the protect him. Stormfly soon came to defend Astrid and the others. After seeing this, Mala was convinced that they were not Hunters and introduced them to sagefruit.
Sagefruit appears in the School of Dragons expansion pack Return to Dragon Island, being sold on Auction Island. While Eret was aware of the purpose of the fruit, the Dragon Hunters were not. The player and Eret use the fruit to distract the Hunters.
Sagefruit appears as a form of "currency" in the limited time Gauntlet Event in 2017. It is used to completely heal a dragon of all damage and remove all status effects. It can be obtained by spinning a wheel and landing on it after winning a Gauntlet Battle. It can also be bought with runes.
