Well, that is really left open to your imagination. Interpret it how you like...I choose to think that she decided to break the mirror so that no other sinister fellows would do what Zant did--try to take over the Light Realm. As Midna said at one point in the game--Light and shadow cannot mix. :( It makes me really, REALLY want a sequel. I've never been so invested in a video game--and it's because I fell in love with the characters (specifically Midna). I miss Midna!
she had too
warp out with midna to another area
Following the final boss fight against Ganon in Twilight Princess, Midna transforms into her original form. Zelda, Link, and Midna gather in the Mirror Chamber, where Midna returns to the Twilight Realm. She permanently shatters the mirror as she leaves, making it impossible to travel between realms.
she just rules her world (but iv'e seen the Zelda website and she comes back)
Probably not (if you noticed midna shattered the mirror of twilight, the only thing connecting the twilight realm to hyrule, in the cutscene after the credits of twilight princess), unless Myamoto decides to do a direct sequel to twilight princess, which isn't totally out of the quuestion; see "Majora's Mask".
you get the mirror peices by finishing the dungeons (desset, time, snow, and sky). its like the thing for Midna. It appears after you kill the boss
The real Twilight Princess is Midna.
yes
The twilight king appears and steals them back then takes away midna's powers. Then link has to be a Wolf and take midna to Zelda and Zelda gives midna her powers and Zelda goes byebye. :3 Then soon you have to get the mirror pices because the guy behind the twilight king Gandrof (or however you spell it) broke the mirror in pices and then you have to find the other 3 pices. and blah blah. that's where i am. The City in the sky. For more info go here. http://faqs.ign.com/articles/750/750737p1.HTML
The Fused Shadows are an ancient power that Midna wants. The Fused Shadows allow Midna to gain a lot of power which will help you out later in the game. Midna will be able to kill Zant & break into Hyrule Castle with it. Hope this helps! ;)
Midna had many reasons for leaving the World of Light. One, she is the princess of the Twilight Realm and she can't just abandon her people to be with Link. Two, after what happened with Ganondorf, she can't afford to risk letting it happen again, because if she lets the Mirror survive, then evil from either Realm could destroy the other. Midna left because she knew there was no other way.
The Twilight princess it Midna. (the girl that frees you from the cell...kinda, in the first wolf part)Sorry to who submitted the first answer for deleting it, but this is a little more...detailed.It's never specified but the twilight princess could be Midna or Zelda.
Zant basically weakened midna's power by changing her form he doesn't want her to interfere in his conquest of changing the light world to twilight.
