Autumvania. One of the worlds where his probes had gone. Before being kicked off the world however it had indeed done it's job. It had detected 1 high level power signature on the planet. If it was as Lord Montreal imagined then there likely would be more than one. So if there was more than one likely there were 100s or 1000s or millions.
Such a number made him want to visit and so uttering the spell for teleportation he would arrive on that particular world. His arrival would not be spoiled by anyone yet hopefully. So his teleportation caused him to arrive in their city.
