Love the Guardians of Ga'hoole books!! had to quote part of the saying about the Guardians.

Where there are legends, the can be hope.
where there are legends, there can be knightly owls,
from a kingdom called Ga'Hoole,
who will rise each night into the blackness and perform noble deeds.
Owls who speak no words but true ones.
Owls whose only purpose is to right all wrongs,
to make strong the weak, mend the broken,
vanquish the proud, and make powerless those who abuse the frail.
with hearts sublime, they take flight...

yeah...epic paragraph right there lol
