Spoilers for the new SCOOP update!
So that's why no cookie discovered the Witch's Castle.
So I know some people will call this as a bandage on the plot hole of is it Witch's castle or Witch' hunt? But let's be real. Of course the witches had put some kind of protection around the castle so it wouldn't be visible.
Like the castle is BIG big.
So of course the witches put some illusion magic so it wouldn't be so oblivious.
And if someone says "But wouldn't GingerBrave and others still know?"
We don't know if in this timeline GingerBrave has met Witchberry cookie. For all we know he fell out of the window without getting knocked out so he probably didn't even meet First Cream cookie. And it seems that Wizard and Strawberry also didn't spend a long time in there like in crwc. So who would have told them it was in fact a Castle and the hunt is just an illusion?
