My theory on the plot so far.

I agree more with OB3LISK's comment, I'm pretty sure nexon is just randomly pulling things out of their.....and we're just putting the "pieces" together into what resembles a story.

I don't think so, Maple really does have a plot, and some of the "pieces" do fit together really well, like the random unrelated Magatia quests suddenly explaining the origins of the Black Mage and becoming a part of the overall plot.

I think Nexon does have an overall plan for the Black Mage story, but most of it is people complaining because the Black Mage hasn't been released as a boss yet.

We still have all the doors in the time temple to explore before fighting the Black Mage even becomes a possibility, what is wrong with them adding more plot? people would complain if they suddenly added the Black Mage as a boss and didn't give it any back story first
