As you descend to the ground here, Groose (remember, the jerk from the Knight Academy?) will decide to hitchhike onto you, making your landing more than a little rough. After conversing a bit, he’ll run to the temple.
After you regain control, use the nearby Bird Statue and speak with Gorko a few times to learn about the Goddess Walls and Gossip Stones – it seems that, if you play the Goddess Harp amongst certain groups of blue butterflies (Blessed Butterflies), you’ll find some special things.
But that’s another section. I’ll tell you of some we come across, though.
Anyhow, go west and ascend the vinery. Afterwards, go to the Sealed Temple nearby.
