Webster Boot had moved to the New World with his parents and brother several years earlier. When his parents died, he was adopted by Isolt Sayre and James Steward and was living at Ilvermorny. For his eleventh birthday, he had requested a wand. Isolt and James crafted a wand for him similar to the wand of his elder brother, Chadwick.
Webster was given his wand two years after his brother. Even though Chadwick's wand was made of ash wood, the exact wood used for Webster's wand is unknown. However, they were both given wands with Horned Serpent horn as the core. Isolt had recieved a dream the evening before Chadwick's eleventh birthday that she went down to the creek to find the Horned Serpent come up to her from the water and bow its head to her. It let her take a shard of its horn. When Isolt woke, she went down to the creek where the Horned Serpent was waiting for her and recieved a shard of horn. She then took it to James who was a skilled craftsman and they created Chadwick's wand. They later did the same for Webster.
Isolt had a protective instinct not to make any more wands of Horned Serpent horn with the exception being their adoptive sons Chadwick and Webster Boot. The wand proved to be adept for duelling when Webster fought Gormlaith Gaunt five years later. Gormlaith did not know Webster and his brother were living at Ilvermorny so they were not sent into an enchanted slumber by her spell and because their wands were made with the horn of the great river serpent they were not made inactive when she spoke Parseltongue. The wand instead recognised the language and made the sound of a low musical note to warn its owner. The sound woke Chadwick and Webster who went to duel Gormlaith.
When Webster helped Chadwick, the twin cores of their wands increased their exceptional power. However, Gormlaith matched their power with her exceptional knowledge of Dark magic which eventually drove the brothers to retreat back to Ilvermorny.
It is unknown what happened to the wand after Webster's death.
