The late Wandmaker Gerbold Octavius Ollivander, always called wands of this wood ‘the survivor’s wand.’ It is said he sold it to three wizards who subsequently passed through mortal peril unscathed. There is no doubt that this wood, coming as it does from the most resilient of trees, produces wands that demand staying power and strength of purpose in their true owners, and that they are poor tools in the hands of the changeable and indecisive. Fir wands are particularly suited to Transfiguration, and favour owners of focused, strong-minded and, occasionally, intimidating demeanour.
