If Dale, Dorwinion, and Arnor can have Carved Bricks, then so can others.
Carved Dol Guldur Bricks could depict a spider.
Carved Taurethrim Bricks could depict an aztec-style Sun like the Stone of Tizoc in real life.
Carved Golden Taur. Bricks could depict a Mumakil.
Carved Obsidian Taur. Bricks could just have a fancy design like the Carved Rohan Bricks.
Carved Morwiath Bricks could depict a Lion.
Carved Obsidian Dwarven Bricks could either have the same design as normal Carved Dwarven Bricks, or could depict something like a mountain.
Carved Glowing Dwarven Bricks could either have the same design as normal Carved Dwarven Bricks, or could depict something like a Mithril Nugget or one of the Seven Stars.
Carved Uruk Bricks could depict the tower of Orthanc.
Carved Angmar Bricks, I have no clue. Perhaps the Iron Crown of Morgoth which was forged in Angband?
I feel like the Taurethrim need a carved brick the most, whether that be for all three types of brick or just one. What are your thoughts?
