IIRC the 'Winter is Coming" was integrated into The Frontier, and now acts as the weather and landscape for the worldspaces. I remember Maybenexttime's original Nexus posts about wanting a large ruined city mod, and one or two screenshots from a long ways back detailing some of what looked like the downtown area of The Frontier in it's original form.
The core team of The Frontier can help you with a more concrete answer though for sure.
