This huge armour-plated imp-shaped creature guards the entrance to
Imptropolis with an ever-watchful eye, preventing anyone from entering who
might prove too dangerous to the city. It looks extremely formidable.
It looks about sixty-four and a half dimins tall, twenty dimins wide, and
five and a twentieth dimins front to back.
It is in good shape.
Impassable rumbles, *Imperial says that al denizens doat easeil place are dangerous to our city, so I will protect Et from them.* in halting, squeakingly-accented Anglic.
Impassable scans the area for concealed persons.
Impassable glares at you suspiciously.
