After several years, many owls take the most invioble oath: the Oath of the Guardians.
I am a Guardian of Ga’Hoole. From this night on, I dedicate my life to the protection of owlkind. I shall not swerve in my duty. I shall support my brother and sister Guardians in times of battle as well as in times of peace. I am the eyes in the night, the silence within the wind. I am the talons through the fire, the shield that guards the innocent. I shall seek to wear no crown, nor win any glory. And all these things I do swear upon my honor as a Guardian of Ga’Hoole until my days on this Earth cease to be. This be my vow. This be my life. By Glaux I do swear.
