How do skills work in the context of the new TL system?
. Skills are available at whatever TL the GM wants them to be. We’re not saying “Physics/TL1 doesn’t exist” because that’s setting-specific. The scientific method could appear as a philosophical movement in a TL1 society and give you Physics/TL1, although it probably won’t be useful for much. Where skills have real game effects tied to TL, this is clear for all TLs. Surgery/TL1 . . . well, it’s not really safe. But it exists!
