The Fire Wall (currently ID 237) seems to just be a red version of dream bricks, since they have similar textures and hardness. However, I've searched the entire repository and found it generates nowhere. Is (or was) it supposed to generate somewhere or be obtainable somewhere or is it now just a creative-only block?

If it's a creative-only block, should it belong in the blocks tab because it isn't found in Vethea anyways?

I can see it as being a trade, though the name is a little odd for a trade.
