Located past the level four shared work area is the office of Isabel Marshall, Head of Ecological Regulation and Protection. One may find it difficult to believe that they are underground, as sunlight fills the room from a large magical window behind the desk. The walls are not decorated excessively, with only a Mappa Mundi of magical habitats around the world pinned up opposite the window. Next to this map is a tall metal framed shelf that holds books and scholarly journals - mostly about environmental protection and advanced charms - and a few of her favourite potted plants. On the coffee table in the center of the room is a porcelain coffee set and various items of confectionery. The table is surrounded by a chic white couch and armchairs where visitors can make themselves comfortable.

But if one was looking to have a more formal conversation with the department head, they would instead sit on one of the two cushioned chairs near her steel desk. On the desk is a two-way mirror and photographs of her family, as well as a miniature figurine of her elderly crup that is usually taking a nap. Occasionally, you may also see a Remembrall if she forgot to did not store it away. Those wishing to speak to Isabel should knock on the door and wait to be invited in.
