Martsia grew up around the oceans and vast seas, and because of that she can usually be found around rivers or streams, hopping and splashing through them and climbing the rocks out as a means of traveling instead of taking bridges. She isn't very chatty with strangers, unless she is being paid for it. Once in an environment with her friends she livens up and starts up on her cheerful banter. Her main goals in life are to someday own a ship of her own, so that she may tame the oceans themselves. Until then she is land bound, and any water source soothes her anxious soul.
She chose the life of the Maurader from watching other sea faring folk use their axes. When she was a child she was sent to live with relatives in Gridania. She feared that she would never see Limsa again, and after the Calamity she aassumed that it had been swallowed by the sea. A few years later she sailed back to her home town as an adventurer, and is more than happy to be back.
