Added "furnishings" to the servants' quarters
Several doors hang loosely on what is left of their hinges, warped and forced half-open by collapsed rubble. Peeking through the doors reveals litter and half-ruined furniture fit for the poor, or perhaps servants who lived in this wing. The door to one room seems to be in better shape than the others, inside the room is more furniture and a rude table with several dusty items left on top: an old brush, a stub of candle, and a small wood bound volume covered in dust, which on examination is a diary. The diary's last entry: "There was more screaming from the Master's laboratory last night. We have been instructed never to enter, but the screams are so terrifying that I shall never be tempted of violating that order in any case..."
I should add some personal belongings or something.
Fleshed out the courtyard battle with the horned giant.
Day lights this courtyard which was clearly once a well-tended garden. Atop a destroyed portcullis lies the remains of a giant; its horned skull and body pierced by numerous spears and arrows. The decayed skeletons of at least two warriors lie heaped as if they were discarded toys: one nearly wrapped around the trunk of a gnarled, but blooming, old tree and the other nearly covered by rubbish in the corner. Old, dried blood covers the paving stones, a trail of it leading through a destroyed gate deeper into the castle.
Lighting needs to be neutral, but fit the mood of the abandoned castle. I'll get to lighting last, still more to work on!
