Unless I'm mistaken there doesn't seem to be much/any lore about this game
My main question is why is hammurabi the (current) final boss? Is he evil? He doesn't sound evil when he speaks, if anything the way he describes it the players are the ones ransacking his pond
This lore could be tied into the bosses voicelines, item descriptions and secret locations
Also could be easily added through NPCs who could also add trading/crafting/quests but that's another suggestion entirely
