I spent the last year or so working this arena. There are a few unfinished aspects, but I may upload more revised versions of this world in the future.
It's not based off of any real world building in particular, but I drew inspiration from the Canadian Tire Centre in Ottawa, and a little bit from Rogers Arena in Vancouver for the interior.
