Helga Hufflepuff's cup is a magical artifact associated with Helga Hufflepuff, one of the four founders of Hogwarts School of Witchcraft and Wizardry. The cup is known for its ability to enhance the drinker's abilities and is often considered a symbol of loyalty and hard work, traits valued by Hufflepuff House.
