The other day I was thinking about resource extraction in the Blades in the Dark world and I came across the use of wood. I guess timber would be a very valuable resource since most of the trees were petrified with the cataclysm. Still, there must be some places from where the Empire is able to extract this kind of resources. I think one of the places this resource could be extracted from is the Dagger Isles, where the book refers to the existence of dense jungles. If you look at the Dagger Isles it is a very small territory so probably it could be deforested quite quickly in normal conditions. One of the things that could make sense is that maybe the cataclysm created certain arcane conditions in this area and it is able to regenerate itself quite quickly. This would make the lumberjack job a dangerous one, more akin to the endeavours of leviathan hunters. Who knows which kind of creatures could populate those dense jungles and what kind of secrets are hidden there.
Did the issue of timber came up in any of your games? If so, how did you address the issue? It would be nice to get more ideas about this.
