Nights who say Ni
These are a group of man-like creatures with a very potent magic. They have the ability to cause audible pain to anyone nearby bye simply saying the word "Ni!". The only person known to successfully defeat a large number of them is the legendary hero Monty Python. One way to survive an encounter with them is to bring them a shrubbery. It is unknown why they ask for this, but it does seem the most effective way to get away unharmed. They are very intelligent and are capable of forming ambushes and traps. This along with their word ("Ni!") makes them formidable opponents any hero should be wary of.
