Cup and Balls
The substitution cipher on the page translates into:
THIS TRICKSTER SHARES HIS NAME WITH THAT OF A SILVER BANDED HOLY RELIC.
That yields the answer "Blackstone", who was both a magician and is a holy relic of the Islamic faith.
This is the skywriting clue:
From Neowin by crimsonhead: Ok here's how i got stage...
I started to convince myself that blackstone was the only possible answer. So I used the code and found the symbols for BLACKSTONE. I then followed a common pattern of Length 5 and Width 4 and tried to connect the boxes. After I did that, I put the letters into an unscrambler and tried all the words until I finally got to STAGE.
VirtuconDG: If you write it as: BLACK
take the boxes from the cipher and connect columnes (B over S, L over T, etc) you get, in block letters, STAGE.
By arranging the ciphers for "Black" and "Stone" above each other, you achieve this:
Combining the top and bottom ciphers together yields the word "STAGE", in block letters.
