Message in a Bottle

The note reads, in fairly good handwriting:

To any that can aid me-

Please, my need for help is dire. A great Skymane holds me captive on an island in the South Seas.

The stars at night are foreign to me and obscured by the jungle trees, but on the clearest days I see Wild Shore to the northwest, and what seem to be large sailing ships to the southwest.

I beg of you, my would-be savior, please help me.

Have you come to free me?
