The legend Pirate and Archer

I like that idea. possibly it may be the re-animated spirit (soul, ghost, whatever) of the legendary pirate that when defeated by the Dark Magician, could have had his spirit torn from his body and sealed in the remains of the pirate legends ship (self assumption that the legend had a pirate ship). Centuries have passed and the seal imprisoning the pirate legends spirit has weakened enough for the legend break free. Since it would be a sort of spirit and having been in contact with the Dark Magicians seal for so long it could possibly have the new Dark element (which instead of a damage bonus on certain mobs could weaken monsters attacking power and defence or even curse them).

Since you mention that, I think Sarah's idea is worth a mention. I really liked her ideas; and what impressed me is how she took advantage of the idea that because you're technically the only character that matters in MapleStory in the questline, everyone can be the same single character of Testonen. An example would be like how NPCs like Mom and Dad do not actually have every Mapler as a child, but the way it exists is that only the player is the child of those NPCs. They are just event NPCs, but the point remains (I'm sure there's other examples of this, but I can't think about this right now).

Here's some of her blogposts: Legendary Pirate: Testonen and The Story of Testonen: Bullet-point draft (chronological) (part 1) . Sad that she gave up on it after all the classes' names were announced.
