Aaquila is an anomaly within House Dougal. First and most obvious she's an Eshu. Secondly, she's a Journeyman and nominally in charge of one of Donovan's Initiatives - the Emissaries. These two aspects, though, make her uniquely suited for her job. She enjoys meeting people and is skilled in conversation and decorum. As a journeyman she is free to wander anywhere and work for any Master.
Aaquila was fostered by Lady Legre from whom she learned impressive powers of organization and how to be a skilled writer. She is also an excellent illustrator and worked on the Catalog of Dreams after completing her exemplar.
