It's unfortunate that this novel is going through an Hiatus, but I look forward for a future rewrite. I will also check out your new story

Magical radios, or in this case 'Wireless' are canon. You can search it up. Just another one of JK's innumerable plot-holes. In this case, I will assume it is completely powered by magic, unlike its muggle counterpart.

It isn't meant to be the Ravenclaw's eagle, keep reading and you will soon understand what it is meant to be.

In my interpretation of cannon, there probably existed a few Dumbledore-level wizards spread around the globe. But considering Grindewald almost singlehandly took over Europe and was only stopped when Dumbledore himself moved. I believe Dumbledore is around the peak power-level in the HP series and wizards like him can be counted on one hand, maybe two at most.

As is custom with this site. I as the Author will give the first review for my own novel. Webnovel standards: Honestly, I think it's great for this site's standards. If you can push through 2000 chapters of MTL faceslaping xiaxian, this will flow as smoothly as butter for your emaciated brain. The major downside is that the update frequency will be very slow, but each chapter will be around 5k words. (Around the equivalent of 5 chapters for the average standard on this site). Average novel standards: As for a analisys with more rigorous standards. The novel is ok. It doesn't have the best grammar, has too many info-dumps in the first chapter, and is clearly the work of an amateur. But can still give an enjoyable reading experience. I hope you give it a try.
