Wondering about the premise behind the newly announced Zelda: Skyward Sword? Nintendo wasn't talking about the storyline behind the game during its announcement this morning, but director Eiji Aonuma held forth about it during a roundtable after the show today. Shockingly, this time around there's more going on than "Ganon kidnapped Zelda and hey maybe you should go save her or something."
In Skyward Sword, Link is a boy born in a floating land among the clouds called Skyloft. Some sort of incident early in the game interrupts Link's placid existence and makes him aware of a land that exists beneath the clouds, one that's pervaded by danger and evil. Link naturally becomes too curious to resist traveling to this lower world, and it sounds like you'll be traveling back and forth between Skyloft and the land below (Hyrule?) throughout the game. The eponymous Skyward Sword is the tool you'll use to do that.
How about that piece of art that surfaced at E3 last year, depicting a spritely young girl bearing the seal of the Master Sword? Quoth Aonuma: "I'll just tell you straight out, the Skyward Sword becomes the Master Sword." I'm pretty sure it's not a spoiler if the game's director says it on the day the game is announced, right?
