Fathered by a pirate captain, Eileen was born into piracy. When Eileen reached the age of sixteen, the British Navy tracked down and surrounded her father's crew. During the battle, Eileen's father forced her onto a lifeboat to escape. When Eileen reached land, she discovered that her father and his crew had been hanged after their defeat. Devastated, Eileen wandered across streets for many days, homeless and starved. Eventually, she came across a poster of a pirate named Runa, who was looking for a crew. Having experienced a life of nothing but piracy, Eileen immediately stole whatever new clothes she could find, and then joined the young pirate captain.
