I live on a fault line along the pacific ring of fire, and so building with wood was an absolute necessity for us so long, as they were structurally more lenient to the constant earthquakes. Even now I believe our old government building is the largest wooden building in the Southern hemisphere (and it’s only 4 stories tall). These days as construction techniques have changed, we’ve obviously built things with concrete, steel, brick, etc., but the wooden tradition remains strong, with a huge majority of modern houses here still being built like this.
That aside, wood was also just a much cheaper material to build with, so it was the most economical material to use for a long time for much of the “new world”.
I’m not super far in, but I have heard it. The first time I remember hearing it is in the opening act when Lin is telling Barrett about you. Also when Sam talks to the marshal about you in Akila City. I suppose there are only so many opportunities for other characters to talk about you while you’re standing right there, but it does pop up, so it’s nice to have the option for those moments.
