OC for Assassin's Creed: Rogue - Jade Mariner Cook (born 1755) was a Templar in the New Generation American Rite (also known as the Templar Ladies) as an explorer on the British side. As the daughter of the legendary explorer James Cook, she studied to become as good as him someday, or even better. She learned a lot about the sea and the sky at the young age of 14, as well as other abilities for an explorer like her. Though she's an arrogant woman, she doesn't just lack empathy but always thinks of herself as the one who deserves everything; it can be seen when she's talking to her father, often forcing him to give her everything she wants.

But even if she behaves like this, she can also have a few insecurities, such as with her chest, which she sees as a curse and something that makes her less perfect in a way but something she can't change. However, such a fact about her didn't prevent her from continuing with her journeys and exploration around the world, continuing to work under the Templar Order's command and the Royal Navy. Oh... And she has an adoptive French sister.
