Terraforming is not a fast process. It takes decades at least - and extensive planetwide facilities. These facilities potentially could be bombed, but they have no military value. The main problem in planetforming in wartime is likely going to be supply - it will take huge amounts of supply to terraform a planet, and especially silver transports are valuable.
I imagine terraforming would be slowed or paused, but not abandoned.
Wide awake in a world that sleeps, enduring thoughts, enduring scenes. The knowledge of what is yet to come.
From a time when all seems lost, from a dead man to a world, without restraint, unafraid and free.
