Demonic Phone Booth From Hell
The shop Teller leads Sameth to is a typical Earth magic shop, full of completely foreign devices, fake animals, and gaffed everyday objects. Teller leads him through the shop to an office, and eventually down a flight of stairs to the basement. Down here is where Teller works on his own props, and front and centre is the phone booth from hell, as illustrated in Teller's notebook.
Sighing deeply, he looks up at Sameth, hoping this guy can do something about the epic leaks that spring from everywhere.
