Everyone who has ever shopped knows about Anna, but no one really knows what she - or they - are. Some speculate that she's a subspecies that can reproduce with humans just fine, like manaketes, taguels, laguz, kitsune, and the like - just without the transformation ability. Others assume that she's just an unwritten rule of the universe - if your daughter looks a certain way, you train her to be a merchant, name her Anna, and get her acclimated to ponytails, and reproduce to make more Annas. Some believe that Anna-ism is just a cult, and the members all use magic to look identical.
No one has yet seen a child Anna, so none of the hypothesis could be tested. In adulthood, Annas all had a ponytail of medium-dark red hair, a love of gold that meant they searched for profits anywhere they could, and were almost always nomads.
Most Annas, despite being ever-hungry for profits, avoid the black market like the plague. &
