Finding the way in
Im on brave, we can see all the assets here.
Just searching for strings related to ctf directly, we find this URL
https://ctf.hackthenorth.com/start
This obviously cheeses it, so the actual way in is found as follows:
There are signs that signal what crystals you should click. The first sign is here:
The second sign is here:
And the last sign is at the bottom
Somewhere near the top of the screen, there are three crystals which you can click.
Click them in the order given by the signs (P,B,R,R,B,R,R,P,B)
At the end, you get this prompt near the bottom of the page. AND also a cookie, but that cookie can be faked so it doesnt matter.
