So the first three pictures explain how he ended up into the world he is in now called Enchantia, where Humans are not a very common place to see (then again, the plane of existence/World where Enchantia is, doesn’t even have humans what so ever now that I think about it)

and that castle is where he meets his fox friend named Fenton Foxington, Who used to be a Druid that haunts adventures from time to time and gave that up 3 years later, to water it down as a short story version

That extra image (the fourth one is just an extension of what happens during the encounter with Claire Belfrey, and Wilbur learns how to do fire magic some how. The whole point of Claire having animosity towards Wilbur is because of him not being from Enchantia and thinks he might get someone hurt.

Anyway that’s my poorly written article made for the backstory and stuff.
