Some interior designs for the inside of Valden's castle.

I always thought of it with a more classical element. At least in the areas the common folk might find themselves in.

So you enter the main doors into the gallery. Heading head up the stairs, you head into the main acess in front of you, pass the large painting at the top on either side and you'll find yourself at the Throne Room staging area.

The spiral staircase leads up the tower.
The halls on either side of the Gallery take you into the wings of the castle (which are mostly offices).
The entryways nestled on either side of the bottom of the stairs branch off towards other areas of the castle (the Great Hall, etc)

I never really delved much into what's inside the castle that much so at least you get a general idea of what the inside looks like.
Hope to get into other areas in the future!
