I was daydreaming on the bus ride home from therapy about a kaldorei druid and a shal’dorei spell blade who duke it out a few times before she (the shal’dorei) realizes she’s fighting on the wrong side and is subsequently exiled from Suramar City, where she begins to wither away. At some point, she is ambushed once again by said druid, only this time she doesn’t really wanna put up a fight and surrenders. He, being a servant of nature, and because she is so fucking pathetic, decides to let her live. And then she just sort of. Follows him everywhere.
Eventually they form a friendship and he teaches her how to live off the land instead of relying so heavily on what little arcane energy she has left.
