The description is:
The lord Ruler's palace loomed like some kind of massive, multi-spined insect.
On the wiki I found:
The Hill of a Thousand Spires. Many ominous towers with large spires of metal on the top.
Here are a few ideas I have been working with so far. I am trying to emphasize the insect and ominous looks. I still need to work on the perspective on a few of them.
