I actually might be able to provide a pre-made family for you. A few things...
- Story arc is in progress (not moving fast)
- Story is actually a bit dark, if that's ok.
- I have a brother & sister pair that I play (one is technically my main). He is still a midlander, she drank a potion to become physically Au Ra with the hopes that it would give her even more magic power than she already had.
- We are very Ul'dahn, but if you want to be in Gridania mostly... this can be easily set up due to the situation.
