I've combined the images of the Tessera that have come out so far that I believe were made from the same picture.
The two images below are a combination of the tessera as it is and the images that were hidden within it
Unbeknownst to me, it turns out that this is the same picture as the Aurora’s game picture, though in a different color.
Tessera is made up of only cut out keys, even in the images in it
These are the tesserae that were used in "why who killed...". I just participated in the tessellation and it was very interesting that these images represented Nemesis and ****.
