well if you havent played twilight princess im minda ruler of the
twili aww the twilight is so beautiful anyway her some more info the
Midna is one of the Twili, a race descended from wielders of powerful
and evil magic who were banished to an alternate dimension by the
goddesses Din, Farore, and Nayru. This alternate dimension, out of
which the sublimated descendants could only exist as shadows,
eventually became known as the Twilight Realm. She remains as an
imp-like creature through most of the game. In recent time, the Twili
have been converted to fearsome "Shadow Beasts" and Midna into an
imp-like form by the self-appointed Twilight King, Zant. Midna reveals
this information to Link in the Gerudo Desert.
After rescuing Link, in return for Midna's help, Link finds the Fused
Shadows for Midna. The power of the Fused Shadows can be used to
destroy Zant, returning Midna and the other Twili to their true form.
Midna does not tell Link, however, that she wants the Fused Shadows
for the benefit of herself and her world. After collecting all Fused
Shadows, Midna is gravely injured by Zant. Wolf Link carries Midna to
Zelda who revives Midna, at the cost of her light essence. After
seeing the unselfish acts made by Zelda and Link, Midna has a change
of heart and vows to help save Hyrule from Zant. The duo now set off
to repair the Mirror of Twilight, a portal to Zant's stronghold, the
Palace of Twilight.
After the Twilight Mirror is rebuilt, having being destroyed by Zant,
the Sages reveal that Midna is the true Twilight Princess and ruler of
the Twili race, not Zelda, who had previously been defined as the
Twilight Princess by Midna herself, presumably to keep a cover on her
identity. Zant, after usurping the throne from Midna, placed a curse
on her that gave her the form she maintains for most of the game. This
curse could presumably not be lifted until Ganondorf, the source of
Zant's power, was defeated.
