Prologue
Ok this is just the basic introduction you'll need to understand what's going on.
Harry has two sisters Amelia (our leading lady) and Cassandra both are two years older him and supposedly twins, they were kidnapped after Lilly and James Potter were killed as they ran after Wormtail and ended up running into a group of death eaters. Cassandra had played little part in the deaths of Lilly and James as she became petrified with fear, but Amelia even at this young age sprung straight into action throwing Cassandra Lilly's wand and telling her to run whilst she went to try help her father, she didn't save him and she didn't delay Voldermort for long although she did give him a nasty scar on his cheek using her father's wand.
Cassandra didn't fight and joined the dark side, ending up being adopted by the Malfoys whilst Amelia refused to give in because of all the horrible stories her parents had told her about Voldermort and his Death Eaters and spent the next four years of her life being tortured as Cassandra lived the free life of a Malfoy and I think you all know what happened with Harry. At eight years old Amelia was rescued by Dumbledore, Snape and three boys, Mark, Patrick and Lewis. Amelia finds out she is part of an ancient line of powerful wizards and when these wizards are grouped they are known as Pacis Tutela, latin for Peace Guardians. The group consisted of the Hogwarts heir Lewis the stuck up but popular for Gryffindor, Mark the Geek for Ravenclaw and for Hufflepuff Patrick the compassionate. Amelia is the heir of an even older wizard named Tarinda Honokaa. This power line comes from the fact that Amelia and Cassandra are not twins they are not even related as Amelia was left as an orphan on the doorstep of Sirius' house at 6 months due to fears she was a squib. Amelia's biological parents the Malfoys and quite obviously as she is the spitting image of Lucius Malfoy.
The colours of Honokaa are orange and silver, the silver due to the fact that there was a supposed love affair down the line with an heir of Slytherin. The loyalties of Honokaa changes with each generation although one thing that remains constant is the power they bring to any fight. Like all the other heirs the heir of Honokaa posses the power of an element,love, Gryffindors are fire, Slytherin is water, Hufflepuff are earth and Ravenclaw are wind. The animal of Honokaa is a dragon.
Each member of Pacis Tutela has an object linked to their special power Amelia has a ring which helps her see through time, Voldermort a gem absorbed by the body to read anyone's mind, Mark had a wand to amplify his extraordinary defensive powers, Lewis a gold chain which helps him break through any ward as he travels and Patrick a pair of sunglasses to see the person's aura and he can sense how powerful they are.
Amelia has always been fascinated by potion making and occasionally even makes Snape admit that she is not awful at it in public. Snape treats her the same as any other student when they are seen in public but when they are alone he is somewhat of a father figure as Amelia feels he understands the hurt within her soul better than Sirius or Lupin although both love her dearly.
Molly Weasley knows that Amelia is troubled and wants to see her looked after so is constantly trying to set her up with one of her sons, Charlie when he is home but otherwise the attention falls on George. All of the Weasleys think of Amelia as part of the family although George has a not so secret crush on Amelia which no one mentions.
Dumbledore is very controlling of Amelia and manipulates her greatly using Harry and her love for him, whenever he is confronted over this manipulation he says it is for Amelia's and the greater good and that one day the world will thank him for it.
Throughout Hogwarts Cassandra and Amelia have had a hostile relationship with both trying to make the other's life a living hell. Lucius knows that Amelia is his long lost daughter but refuses to acknowledge it other than stating that she has potential to be so much more than a Gryffindor. Draco has a idea that Amelia may be in some way related to him because of her looks but fear of his father stops him from pushing the matter. Narcissa Malfoy has no idea.
Now this story starts during an Order meeting, Amelia and the rest of Pacis Tutela were allowed to join group are discussing whether or not Amelia should return to Hogwarts or stay back and fight along with the other members of the Order.
