In several fantasy books, the main hero often sustains injuries in their quest to save their respective worlds.
In The Lord of the Rings, the protagonist Frodo Baggins sustained a number of physical and spiritual injuries throughout his quest to destroy the One Ring. On Weathertop, he was stabbed by the Nazgul with a Morghul blade. Even though the blade’s poison was healed, the injury itself will never fully heal and Frodo would carry it for the rest of his life. At Mount Doom, Frodo had one of his fingers bitten off by Gollum, earning him the nickname Frodo of the Nine Fingers. Finally, Frodo’s mind and spirit was deeply scarred after carrying the One Ring for so long during his quest.
During his final fight with the Shade Durza, Eragon sustained a cursed wound on his back that hindered his progress as a Dragon Rider. Even though the wound was healed and the curse lifted, it still played a significant role in Eragon’s development.
In addition to having his face scarred by a Wildling’s eagle, Jon Snow endured a traumatic experience after being betrayed and murdered by his own men. Not only did he sustain mental and spiritual scars due to experiencing the pain of death and the rapture of rebirth, but the stab wounds he sustained would never fully heal.
Rand al’Thor, the Dragon Reborn, from the Wheel of Time lost his left hand after having a mystical fireball thrown at it.
Overall, the injuries and pain that fantasy heroes play a significant role in their character development and serve as permanent memento of their adventures. I am planning to be in keeping with this tradition and have the main character in my Dark Ice Winter series injuries during his war with the Bauk horde.
