MAYBE. Moving the hole else ware may have moved it somewhere so utterly far from the area where everyone is. Alternatively, it may have re-unleashed Nightmare, but in THAT HIGHLY UNLIKELY INSTANCE, I have taken the liberty of making sure the Magnum Opus can blow straight through him and seal him in a bullet. Nobody's going to screw with it at that point.

EITHER WAY IT MAY TAKE A WHILE OR NO TIME AT ALL, so just be prepared, OK? Keep the gear on, maybe chat with Len quickly, retrieve Mr. Nyanyan, AND RETURN SAFELY!! THE LAST PART IS MOST CRITICAL!!

I'm going to be DESM'ing up the KotH Dimensional Hole so all is nice and neat in here, so give me time if you need it. Go through the dimensional portal at your leisure, and remember where it took you. It should be stable now...Still, don't stay too long between dimensions! You never know!
