Tune & Fairweather hid a little easter egg in Astora by Yang ShaoXuan (Instagram). It is featured in Soul Arts on page 120 but like many other artworks also in the rose window starting off the Dark Souls chapter on page 105.
But the version in the rose window is altered. The circle was turned into a symbol of two joined snakes.
This is a reference to Tune & Fairweather’s logo which features two snakes and also a reference to the Caduceus Round Shield which is also referenced in You Died.
Discovery of the altered image in the Tune & Fairweather Discord.
