How about... When Ekimu fought Makuta, the Protectors all lived in a city, and when the ground split open, the Skull Spiders came from the gap, forcing the Protectors out, and there's a refuge inside the city where everyone would be able to be safe from the MoUP, and so because Makuta's waking up, the Protectors want to get back into the city so that they can survive his awakening? Maybe? I was thinking more of maybe the fortress/city was where the mask makers made their masks before the catastrophe. The Protectors/natives could've lived there but were driven out after things went bad. It could also be like the Golden City from Exo Force. On the topic of printing: I don't see why everyone's complaining. It looks great! It's a little disappointing that Kopaka has two stickers, but you really don't have to put them on if you don't like them. Where do the stickers go anyway?
