Highest Rank: #290 in Fanfiction ××× "Its a mad, mad, world out there, girlie. And your kind just makes it madder." Everyone has a lock. Some people are lucky enough to find someone who holds the key. Opal's lock has been rusted and unused for years. But when a bipolar skeleton wipes away the dust and doesn't mind the rust on her edges, she can tell she's in for one hell of a ride. ××× "That star looks like you." He said randomly, guiding your hand to see the star he was looking at. "How the hell is a star supposed to look like me?" You said, leaning your head on his shoulder. He ignored your sarcastic response and mumbled quietly to himself, "It's the brightest one of all." ×××

You wanted to help but it was too late... So, you left. Tears filled your eyes as you thought of the one person that needed you the most... They were gone and it's your fault. You ran and ran trying to escape reality. You thought if you could run far enough or fast enough that you wouldn't have just lost everything that made you want to live and exist... but you did.

[SEQUEL OF AT THE SURFACE, IF YOU HAVEN'T READ IT, READ THAT FIRST PLEASE] Summary: (y/n), even to today, was still a legend. Everywhere she went, people would honor her and still bring her gifts. All of this, because she apparently "contributed" to locking those savages away. Oh, how she hated what they thought, but they will never know the truth, and it would be better if they all didn't. Now we are 20-something years after the war, she's a divorced, single parent of a 14 year old girl. But her daughter isn't exactly what she had imagined her to be, in fact, her birth-daughter looked nothing like you or your "spouse". She looked exactly like the girl with rosy cheeks. But she didn't act anything like HER. She was a nice, and quiet girl. Of course, she grew stubborn like you, but regardless of what happened, she was always kind. So, it confused you, but you were happy with her. It's just when she disappears, when things start to twist. You were alone in this world, without parents, without a spouse, and no one to really trust. Little do you know...her disappearance, was for the better.
