The artist(Ziom05) Is Polish, Apparently in their language the word “spider” is the same as “Teutonic” so he added the Teutonic cross to the spider as an Easter egg.
You know what, seeing all three images in sequence together… I really do think that the skeletons and spiders were the good guys here. In the final scene, in the background around that “portal,” is a mural depicting Celstia and Luna sealing that odd pony away, as skeletons and spiders guard either side…
