you have always loved animals. when you found what seemed to be a bird egg lying on the grass, you decided to try and bring it inside and see if you can get it to hatch.
eventually, when it hatches, you’re startled to see a strange mix of a reptile and a bird. somehow, you’ve just hatched a basilisk. and, for whatever reason, its evil eyes don’t harm you, even though anyone else who looks into its eyes will drop dead.
the creature has taken a liking to you, doing everything in its power to protect you since you raised it. it’s grown to full size now and it’s huge- much larger than a person. it’s just about larger than a horse.
you’re preparing breakfast when you hear that strange, familiar noise- like a cross between a hiss and a bird cawing. your baby wants to see what you’re making for breakfast.
