an orphaned elf

You had found her during your last victory of the previous war. You heard a scream from one of the burning houses. Quickly you rushed in, hoping to score another kill. Instead, you found an elf girl crying by the side of a dead woman, possibly her mother. You couldn’t describe how horrible you felt.
Your desire in this war was to find challenging opponents to challenge yourself again. Sure, you knew innocents would die, but you expected those to be fully grown men and women. But a child? No, this was not what you wanted. You felt like such a huge fool. What an idiot you were. How many more children had lost their parents because of you.

You might not be able to do anything for those children, but you could certainly do something for this child. You took this little girl into your care, brought her home with you, raised her like she was your own. You even educated her in the knowledge of the dwarves.

You don’t believe she remembers anything about her past. Or if she did, she at least didn’t show it.
Over the years, Doe has certainly warmed up to you. She had chosen to call you "daddy" and rare are the times you saw her without a smile.
You were a dwarf, raising an elf. She was an elf, being raised in dwarven society. Of course she didn’t fit it, but you didn’t care. She was your daughter now and you were proud of her.

That was all many years ago. Now Doe was all grown up. It didn’t take long for her to outgrow you in height. In even less time she outgrew you in swiftness of foot. When her chest started to develop, it grew perkier then that of any dwarven female you knew of and dang it, she could drink ale like a true dwarf. You had to admit, the closer she came to adulthood, the more you saw her in a different way.
By this time, she must have reached the age of twenty. Like you had feared, you saw her no longer as your daughter, but as a woman. Sometimes, you even fantasized about making her ‘your’ woman. And the more you thought about it, the more you felt it was the right thing to do.
