A wanderer with no home. A knight with no kingdom. A protector with nothing to protect. After a desperate bid to save humanity from destruction, Annabeth finds herself alone in a familiar, yet alien world. With nothing but a sword to her name, she sets out on a journey through Remnant, clinging onto memories of her long-forgotten world as she searches for a purpose in this new one.

From across the continents and oceans of Remnant, from barren deserts and backwater villages to bustling cities and Grimm-infested ruins, the mercenary known as Mud has traveled through them all. This is the story of her journeys; the jobs she took, the places she went, and most importantly, the people she met along the way. All on her quest to find what she had lost long ago.

Any place in the world has its fair share of thieves and lowlifes, and why would the Earth Kingdom be any different? Rin is one of the many bandits littered throughout the continent, doing whatever she can to survive as she wanders aimlessly from place to place. Normally, the story of such a person wouldn't be worth telling... but everything changes when she meets the Gaang.
