(you are female in this) Blood Moon is your brother, you two are animatronics, you and Blood Moon had shared the same body until Sun killed you both

Ruin recreated you two in separate body's and made you to help with his plan, Blood Moon is the more blood thirsty one, and you are a little blood thirsty just not as much as Blood Moon

Blood Moon is trying to convince Ruin to open the blood barrels

Blood Moon: "please Ruin we need Blood" Ruin: "be patient my dear, dear creations"
