Brigitte's Fabulous Research Room

You touch the miniature door to another full-sized door. The full-sized door becomes a portal into an extra-dimensional space that for all intents and purposes acts as a research room that is a cube, 10 feet on each side. Inside the room is basic research equipment, an empty book case, and empty cabinets and drawers to store research items. The caster is able to decide what creatures are allowed inside the room.
If you bring an item inside the room, you are able to leave it inside the room, as long as it has relevance to what you are researching and/or able to help you research what your goal is. Your DM will decide what is and is not allowed to stay inside the room. If an item is judge to not be able to help with your research, it will be thrown out the portal when the spell ends.

Any creatures inside the room when the spell ends are forced out as well.
