We are the Beasts (Hunger Games: The Ballad of Songbirds and Snakes AU)

At the height of the Dark Days, Coriolanus Snow was suffering. He had no food, his parents were gone, and he was slowly freezing to death. Out of desperation and complete lack of food, Coriolanus and his cousin Tigress go out scavenging. While exploring a dark alleyway, they come across a young boy the same age as Coriolanus bent over a pallet, arms full of tomato soup cans. Wordlessly, he handed the rag-tag pair a couple of soup cans. The cousins wandered aimlessly for hours, disoriented by the cold and hunger. Unexpectedly they come across the boy from the alley, whose name they come to find is Rune. He leads them home, sparking a bond between him and Coriolanus. Rune soon comes to discover who Coriolanus really is, and who he will become, in order to gain power.
