[Manor] A Fickle Guest

Adventurer, I've just received an update on our pressing matter! The guest I've been waiting for is currently in Calpheon. I didn't see his ship come into the port. I wonder how he got through? A Night Crow flew in last night with a message. To bring Gold Bar 100G and seek him out. Hmm... Adventurer, could you follow the suspicious instructions of this letter for me? I think it'd be better for someone as strong like you to take on this endeavor, Adventurer.

Could you obtain Gold Bar 100G and follow the instructions of this suspicious letter?

I thought I made it clear that I wanted to meet with Grolin in person. If this is his response, then I cannot hand over the promised item.
