Machines of War
Tech Scavengers are people who go through the destroyed machines and ruins of the ancient people in order to scavenge pieces of tech and documents. They go through the large mechs and other ancient structures looking for things people will buy.
They sell the ancient documents to the Temple. The Temple is always looking for new things to add to their sacred texts and will often pay a high premium for them. More affluent members of society will buy old disables technological trinkets. They will buy dead Soma Cube pieces to be a status symbol and other dead technology to use as jewelry and decorations. If they come across any working or powered technology the Formica will usually pay them top dollar for it.
Despite many people buying their wares they are often shunned in large cities and by church members. The smaller towns are usually nicer and will sometimes offer a meal or a place to sleep to Tech Scavengers.
