The main problem with the second one is the Civilation they are at war with, perhaps the enemy civ is in the andromeda galaxy, My civ could be a fleet of ships that in order to escape the clutches of the other civilization went through a wormhole and then collapsed the wormhole in order to build an empire capable of fighting back. Perhaps they want to unite the galaxy into a massive Military empire or something.
