One day, a mercenary walking through the woods after returning from battle hears a cry for help. He rushes towards the voice and happens upon an elven woman who is about to be assailed by a ruffian. He defeats them and helps her to escape. "Oy, elf girl, what are you waiting for? If you stick around here looking like that, you'll end up in the same situation. Hurry up and head on home." But in a faint voice she replies, "Home? Where is that? And how do I get there?"
It would seem the elf does not have a place she can call home. Much like the mercenary lost the place he used to call home. Their shared pain draws them together and is slowly but surely healed by one another's company.
