The Notes:
Really, they are going to OPEN more questions than they answer, because they involve areas of back history the story has not touched.
HOWEVER, I do delight in teasing, so:
For the Heraldic Devices:
The Dragon on Gold was for West Shand, Drakish Protectorate, Second Age.
The Cresent Moon on purple: was for East Shand, Paravian - Second age.
The crescent moon and black falcon on violet: High King's Device, East Shand, circa Third Age 1.
The gold and purple chevrons, Amalgamate Territores, Shand, circa Third Age 670.
The notes on the drawing in the Paravia Sketchbook:
TAWBAS INN circa Third Age 5918, Sanpashir, Shand copyright 2013 (It was completed early this year). The watercolor was taken from that drawing and hand painted on stretched paper (Arches) and will, perhaps, have figure(s) added for the cover image.
Tawbas Inn subsequently burned down for a violation of terms, and was never rebuilt, the territory being subject to the tribes, and a site of their sacred rites. The well's foundation remains in ruin, and is marked on the Map in Initiate's Trial - the site is also where Elaira met the tribal eldest, and if you wish to know why that place it is historically relevant to the books, proper, you will have to read Child of Prophecy.
