The Room of Requirement is a magical room in the Harry Potter series that is located in Hogwarts School of Witchcraft and Wizardry. The room is enchanted to appear only when someone is in need of it and the person must state their specific need to enter the room. The Room of Requirement is often used as a storage space for various objects, but it can also be used for a variety of other purposes, such as a hideout, a practice room, or a place to hold secret meetings.
In Hogwarts Legacy, the Room of Requirement will be your personalizeable home within the castle. Here you can conjure different types of working stations and furniture. The room can be completely customized by changing the architecture of the room, and customizing the furniture.
The Vivarium is a unique feature that can be accessed through the Room of Requirement. It serves as a place where players can view and manage their collection of magical beasts, which they can acquire during their journey through Hogwart's Legacy.
