Reathbane

The Inspired Quarter
Before you finish the quest Eye of the Titan, he will only tell you:
 * Reathbane: You want to charter a boat?
 * You: No, there's no particular place I need to go to.

After completing Eye of the Titan, he will accept to transport you:
 * Reathbane: You wanted a guided tour? Many giants ruins to see.
 * You: I'm interested in the Isle of Forgotten Dreams—you took Gerald Goodblade there, correct?
 * Reathbane: The Isle of Forgotten Dreams... many old haunted giant ruins... many Titan remains. Want us to go there?
 * You: Yes, take me to this place (Sent to the Isle)
 * You: No, I'm not ready yet (Stay at the Quarter)

Isle of Forgotten Dreams
At any time he will allow you to take transport back to the Inspired Quarter.
