*DISCLAIMER* -This is an AU of AOT where there is an island next to Paradise, it is called Magnolia. It has Isabel Magnolia, one of Levi's gang members in the Underground, as one of the people from there. The Marleyan soldiers and soldiers of the three regiments will not be using ODM gear, they will be using armour and swords. The Magnolian Kingdom is allied with the Marleyan army, and go at war with Paradise, and they use titans to help fight in war as well. This will not be following the main plot of AOT, and a lot of big changes will be made to fit this story.
*STORY LINE* - Lisbeth III, or Queen Magnolia of Magnolia, sneaks herself into Paradise under the identity of Rika Kim. She finds herself climbing the ranks of the Garrison regiment. As she does so, she gets word that a woman, of which Rika was a stranger to, had died to the titans, along with another man she had been working with. It got to the Garrison because those people were rescued from the Underground. The woman that died was Lisbeth's sister, Isabel Magnolia. Still under the identity of Rika Kim, she suddenly disappears from the face of the earth, and takes an offer to the Marleyans, to declare war with the people of Paradise. But as she guides her army from her throne, a man under the name of Levi Ackerman reaches to her. Lisbeth is drawn towards this man, and tries to strike him down. But in the process, the man is under the suspicion that she had kidnapped Rika Kim, as she disappeared right when Queen Magnolia had declared war. What happens when Lisbeth has to be in two places at once? Will she choose to abandon her kingdom for a while to keep her dignity? Or will she stay an oceans distance away?
