Dalra

Her position was granted to her by proving her skills & knowledge worthy. Her responsibility is to provide a surplus supply of blood, a blood bank if you will. But Darla loves her human girls (blood bags). She adores them & has given them a purpose in this world. She offers them another chance at life & provides them a home, food, clothing & even aides them in making their dream come true; in return, they give up their entire being. She does nothing by force & wishes that her girls are obedient.
