As mentioned, there's nothing on TMView or even the New Zealand Trademark Database under this name. I've searched for the name itself, checked everything under Blizzard and it's representatives, and even taken the case number provided in the PDF and searched for it manually, but it comes up as an error. When you search any of the other listed case numbers, they bring you to the trademark filing immediately. The only exception is 'Council of Glades'.
There hasn't been any success in finding where the OP might have found this, and the trademark isn't on any official channels so far. Until there's evidence it could be real,
I would seriously hazard anybody against getting excited or hyped. This could (and very well might be) fake. It's just a PDF, not an official filing. I cannot stress that last part enough.
