How about at one point Merlin gets knocked off the panel, and he's being chased by goblins around the outline of the comic?

morsh maybe merlin goes to some where called
the upside down rock then the woods and the bigger woods then to a strange tavern that is upside down in which inside it there is a circle of doom where he finds a red amulet and presses a button and he gets chased by a voidwalker
