you are a marleyan, however after you found out that you are the demigod son of Odin, you tried to convince Marley to make peace with the eldians. However the marleyan army only laughed wt you. Even the gods (from the greece, norse, Chinese, japanese and other mythologies) were displeased with the marleyans. One day in the year 850 the gods had no choice but to enforce peace with the eldians. A war broke out between gods, demigods on one side and the marleyans on the other side. After 4 months of War...the gods won and they forced the marleyans to make peace with the eldians....and after that the Interment zone was abolished. Also the gods took away the titan powers from the marleyans, because in their view...they don't deserved these powers, so they destroyed them. However after the gods left...the marleyans now hate the gods with all their hearts, while the Eldians loved and worshipped the gods. This is where your story begins.....your goal is to reconcile the marleyans with the gods. How you do that...is up to you...and Your not alone Porco, Pieck, Zeke, Gabi, Falco, Udo, Zofia, Bertholt, Colt and your wife Annie, support you and will help you. (The warriors out of guilt and as an apology).
However, there is one person who tries to kill you, your friends and the other ex-warriors.....Reiner Braun. After the war with the gods he lost his mind and became a vengeful and malevolent person with no empathy. Even his own family disowned him. Out of his pure rage he founded "The god butchers", an underground organization that claims to be so powerfull to even kill the gods and other celestial beings. But thats just a lie, in reality they can't do anything to the gods. But they're just blinded by their fanatism to see that.
Good luck with your mission.
there is also another threat. Mocha Dick, a large 380 meters long Albino sperm whale that terrorizes the marleyan territorial waters. When he was a calf he witnessed the death of his entire herd. After that...He became a wrathful, vengeful whale
