Powerful siblings

Pearl was starting out of the window looking at the moon It was a cold night and snow was falling softly on the ground outside and frost covered the windowsill then the door to the library opened a boy with black hair and green eyes walked into the library. "Sister it's getting very late why don't you go and get some rest you've been at this since dawn." He said softly "I guess you're right Rex as always maybe I should go to bed." Pearl said "what are you doing in the library anyway?" Rex inquired Pearl got up and started to put the books back on the shelves where they belong then turned around to look at Rex. "You know perfectly well what I'm doing in here I'm looking for information on where our parents are they've been missing for nine years." Pearl said "I know and we'll find them but you can't do that if you're exhausted and hungry now come down for dinner then you need your rest." Rex said "Your right again Rex alright I'll be down in a bit." Pearl said Rex nodded and left the library Pearl fixed her long black hair and put it in a braid then she went to the dining room to eat. "Good evening everyone." Pearl said They all said good evening to Pearl as she sat down to the right of Rex to left of Rex was Lewis he had blonde hair and blue eyes sitting next to Lewis is Ruby with her blonde hair and green eyes. "Lewis can you read me a story tonight." Ruby said "Of course I will little sister I always do." Lewis said Lewis may be fifteen but he'll still read to his ten year old little sister Rex is sixteen and Pearl is the oldest at eighteen once dinner was done everyone went to sleep not knowing the dangers they'd have to face tomorrow morning.
