How to Find Mother Ella's Living Quarters

A D&D party finds themselves in an office that is labeled mother Ella. A hidden button on the underside of the desk reveals a silver key and a picture of what appears to be young Asaphy. Wax droppings indicate where the candelabra has been, but they're not even like talking in character. Do you want to open this door like I mean y'all are talking inside of the door? So if someone was there, can I sneak under the door to see what's in there? Are you that small? Yeah, well that you could look at that little critter go Oh my goodness, that is adorable.
