From http://www.wowwiki.com/Swift_Flight_Form/Questline:

Fly to the Vortex Pinnacle and kill an Aethor Ray (near 32,51). Drop rate on the eye seems to be 100%. The only difficulty might be finding a clear spot to fight one in, so you may need to clear a spot in which to fight. The boars that wander around are KoS, but the rays are not.

Once you have an eye, use the stone. You'll get a five minute buff that will allow you to see the arakkoa spirits wandering the pinnacle. If you talk to one of the spirits, they'll tell you to look near the ogre village. On a side note, the ogres are relatively friendly, and offer some quests of their own.

I found Sai'kkal wandering outside the ogre village, near 31,56. Once you find him, talk to him and listen to everything he has to say (you'll automatically get a buff that disguises you as his son):

Rokkaram, is that you?

Forgive me for questioning you, my son. My sight isn't what it once was, but the raven has blessed me with a long life.

Soon it will be time for you to take my place. I have taught you all I know. My only regret is that I didn't prove worthy enough to recover our sacred Book of the Raven.

The true believers have lived in shame since the day our treacherous cousins in Skettis stole the book from us, shattered its tablet, and buried the fragments in their wretched city!

Pray that the raven will choose you to restore it, my son. Be faithful and remember always the prophecy, "From the dreams of his enemies shall the raven spring forth into the world."

Once you've listened to everything, fly back to Evergrove.
