The Twins have come out victorious yet again.

[Alphonse]

Group of obsidian builders?

I can't release the lore until revamped but I have it all written out.

Basically natain and Alphonse are apart of a race of builders who learned to use magic to shape Obsidian into fantastic shapes. They are lost to them, but hope that they can attract their lost kin's attention by building magnificent structures from obsidian.
