Shad examines the Ancient Sky Book
In
Twilight Princess, the
Ancient Sky Book is a book written in the
sky language and the key to restore power to the
Dominion Rod and reach the
City in the Sky. To achieve this, Link must find all 6 missing
Sky Characters hidden beneath the
Owl Statues scattered across Hyrule. Link obtains this book from
Impaz, the old woman who lives in the
Hidden Village.
Trivia
The symbol on the cover of the Ancient Sky Book is similar to the symbol that is on Farore's Pearl from The Wind Waker.
