Can someone explain this to me?

She's not an elf. And what in the world does security have to do with being an elf?

Not what I meant.

I meant she could have lived a long life as an elf, and maybe she was directly involved by losing family in the war with the Black mage so she became traumatized and became obsessed with trying to be safe. She always says "We lack man power, maybe we should get people from other places *bla bla bla*"
