When you give Sadha the Swornbreaker she says "you never cease to amaze" even though your journies were seperate and Ghanga in Driftwood clearly knows how important you are when he decides to address you formaly.

It is my belief that dreamers can also use their abilities to learn about past or curent events and this is backed up my the Owl mistress in Kemm's Mansion who says: "the house of dreams is contacting dead warriors".
I can't say if this is true or how accurate such visions might be, but it definitely fills some plot holes.
