Baci is the leader of the Ametum. She is an apothea and a turkey vulture Zoan. On the year 899, she started a cult around purity and cleanliness. Thanks to a influx of hundreds of spirits into her soul, she ascended and gained a lavender-colored halo in the shape of the alchemical symbol of soap, an angled square with ram horns.
Baci continued to teach people the ways of her religion, Ametism, combating pollution, miasmas and infestations. When aphanoses (caused by viruses unknown to people) started appearing, Baci also decided to eliminate all of them as well.
