Many years after that the humans got into an argument with some aliens, from the outer reaches. Something about stealing their planets, they had been keeping as overflow planets for when they needed to expand. As far as everyone in the region of space we were in were concerned, the aliens hadn’t told any of us and hadn’t even landed on them to claim them and it was us that had terraformed the planets in the first place. So in a short time they were at war with them but humans couldn’t fight very well so they started to hire some of us for defense, which was OK with us as it meant we suddenly had something to trade for their goods such as art and plays and songs their food was crap so that was no good. However we found lots of other things to trade for, a thing we loved the most was their war films they were hilarious, when I first saw one I nearly died laughing it was brilliant. We had worked hard bringing the humans up to speed on new technologies and they thought it was great at first until they found out everyone within galaxies of them had the same problem. Once weapons reach a certain level they become useless because everyone else has a defense against them, so it came down to brains and brawn, no luck for the humans as they were not only small but weak, lucky for them they were smart or they wouldn’t have lasted.
