The page titled "Consensus Omnium" instructs the reader to create magic squares for Altair, Sirius, and Alpha Centauri. All three names specify constellations. Above the instructions is a soundbar that seems to play morse code and below is a box of undeciphered script that contains a link.
In order to complete this puzzle, the reader must make a basic magic square from the numerical values of the words. Once a square has been made, a sigil can be made using the techniques explained here: http://www.spiralnature.com/magick/squaresigilseal/
Afterwards, a picture of the sigil should be posted on Twitter, with SVV tagged in the post.
