The worlds listed a being untenable and abandoned are:
Albion
Atreus
Circe
Colleen
Delios
Eden
Ironhold
Lum
Marshall
New Kent
Paxon
Priori
Shadow
Tanis
Tranquil
Vinton
York
Some worlds as to New Kent, Vinton and York are described as being radically damaged by military action.
Others are described as losing their population due the WoR.
But others simply appear as being abandoned (e.g. Ironhold, Paxon).
I think there could be most of the planets resettled or at least the raw materials still there could be used.
