Do you think there any castles or fortresses in the Disputed Lands not directly linked to an existing walled settlement? Are their any in the lower Rhoyne territories controlled by the Volantene?

Disputed Lands – maybe, but there’s no textual evidence. Likely depends on terrain – are there any hills or fords or other geographical features which would make a fortress useful? Or is it a featureless plain where mobility and flexibility are key and fortresses just limit you?

Lower Rhoyne – far more likely, although again, no direct textual evidence. Forks in the river, fords, bends in the river where the speed of the current changes, etc., rivers offer far more locations where one would want a fortress.

What were Griff and Young Griff up to for the 12 years before Tyrion joins them? Hanging out on the Shy Maid, aimlessly sailing up and down the Rhoyne? 

 Varys says at one point that “[Young Griff] has lived with fisherfolk, worked with his hands, swum in rivers and mended nets,” so it does seem like Young Griff spent a good deal of time on the Rhoyne living and working as a fisherman while being educated. However, given his language skills, it’s quite likely that he spent a good deal of time working in the coastal trade around Pentos, Tyrosh, Myr, and Lys, although he seems to have avoided Volantis and Slaver’s Bay.
