This (a better longer version than this) will probably be part of a large book series
in Coldharbour about how the IC will be taken when Molag Bal comes.
(After Molag Bal's army has taken the city and stand before the Imperial Palace.
"Let's take this tower apart!" The demon general shouted.
"No!" Molag Bal exclaimed, the air seemed to turn to ice in his presence. "You will not tear the tower down. It shall be My palace."
"My Lord," The general began. "To the mortals this is a symbol of hope. Surely destroying it will..."
"You question Me?"
"No. Of course not my Lord."
"You understand nothing. It is because it is a symbol it must stand. We must corrupt it."
"What are your orders, Lord?"
"Bring to me all the mortals. I shall grant them immortality. Then you will take them to the top
of the tower and squeeze the blood out of them. Let their fluids and entrails pour down the sides
of the tower and do this until the every stone is stained with death and foulness. Then it shall cease
to be their symbol, and be the Palace of Molag Bal."

This is a sample of what the White Gold Tower would look like in Coldharbour. I only show
a little bit of it because I didn't do a very good job on the other parts of it. Even here you can
see I got a little overzealous and accidentally made it a little too orange.
The idea as described in the story is that the tower, in particular, has been splattered with blood
to make it more demoralizing for the imprisoned mortals. The city basically needs to be very dirty
and every now and again blood-splattered. We can then add some zombie corpes like you find in
Necro lairs. We'll probably have two separate texture versions of the architecture so we can mix and match,
a blood splattered version and a filthy version.
