Comment by Yaz Bordeaux on Fairy Tail: 100 Years Quest - Chapter 137

@Yaz Bordeaux tldr 
the guild is an illusion made by the dragon 
at least that's what I got

@Yaz Bordeaux Could something like Plato's cave allegory.  The world we see is the the shadow and world of concepts is what casts that shadow. There's concept of red and everything red we see are manifestations of it. Viernes ascended to that plane of existence and seems to have some limited ability to influence things there. Maybe he for example merged himself with the concept of guild Gold Owl and thus became able to influence everything associated with that guild, like by empowering and resurrecting them and influencing their wills and personalities and is able to do all that as long as they recognize themselves as members.
