This was before she became a pirate. One of her hidden past, perhaps.
Aularen used to be a cook's apprentice in a shady tavern, contented with filling the stomachs of scurvy pirates. One fateful day, the day she found her rat in fact, she got into an argument with a nasty looking pirate about how his mutton leg was cooked (it was not well done, as she was distracted by the rat she found scuttling in the kitchen). Agitated, she swung the femur at him, sending him flying out of the tavern. The audience cheered enthusiastically and a fight ensued, which Aularen, accidentally, won. She later found out that the pirate was the captain of a ship, the Late Delivery, and that his crew decided to abandon him and take her as their captain. She was fired for her actions, but won a ship, and a crew.
This is however, just a legend, about the captain of the Happy Delivery. Only the pirate herself knows what really happened.
