They hid up in the hills. They built the fort around them. They didn’t wait for the others. They knew they would come up the hill too eventually. Months, years, decades went by and no one came up the hill searching for their protection, for a safe haven. So, they decided to find out what happened; they knew the others were dead, after all back then the others were weak, slow, and ill. As they entered the town, a new breed of others lived there, fully functional and capable. Time had made them evolve, change, adapt. The strong ones were now the unadapted, the odd ones. They managed to escape before; they didn’t wait or help for the weaker ones, it was the survival of the strongest, they defended. However, being strong means changing, not hiding.
