Warren the 13th is the 13th Warren in a line of hotel owners.  His father Warren the 12th died when he was young and his uncle Rupert runs the hotel until Warren turns of age.  His uncle is lazy and worse is married to aunt Annaconda, an evil witch who might have only married Rupert to find the All-Seeing Eye which is located somewhere in the hotel.  A mysterious guess who doesn't speak arrives, after years of no one coming to the run down hotel.  Soon after Annaconda's sister witches; Scalene and Isosceles arrive to the hotel.  They are followed by all the people that they told about the All-Seeing eye, each one with a different idea of what it might be.  Warren must find the eye before anyone else, or according to a line of Warren's the 2nd's journal the hotel will fall.
