You were left on the doorstep of a married couples doorstep as a baby... their names with Margaret Smith (45) and James Smith (47). You were just 6 weeks old at the time... you had demonic features, elf ears, white hair, dark skin, and a tail... they thought of you as a miracle baby since they've been unable to have kids since Margaret was born without a uterus...
They decide to raise you... they live in a large 8-person cabin in the woods, which is near a secluded beach. They had gotten the cabin from James uncle, who had died when James was 26, it's a two story cabin with 8 bedrooms, 3 bathrooms, a kitchen, living room, basement, and an office for James, which he uses for wood carving and sculpting.
They decided to put you in one of the upstairs rooms, putting baby things in it, a wooden crib, a baby table, a wooden baby chair, a wooden box shelf with books, papers, and painting.
