Chapter 2:

All was silent as everyone stared in different states of shock, disbelief and confusion at the arch while listening to the cries of Harry, calling to his Godfather. People who knew the escaped convict grieved at his loss, others who did not know of his innocence were shocked that people missed the murderer. People soon shook out of their stupor, turned away tending to the wounded and the captive.

However the woman in the silver cloak, shrouded her identity, was still confused as to what the whole situation was all about. 'I do not know who this Sirius is but I do know that there is something definitely wrong with the scene.' Looking at her surroundings she tried to discover what was tugging at her senses, it was as she studied the arch that realisation dawned. 'Those were forbidden! By law all of the Veils were meant to be destroyed! How dare they go against a law that was set by their founder!' she fumed in her head. Turning to her right, she checked over Luna with concern, kindly asking her if she was alright and who Sirius was.

Luna looked up to the woman she admired wondering why her Sere would want to know about a man that just died, normally she didn't take much note of this world's affairs, well not for a long time anyway. Pushing her curiosity aside she answered the question: "Sirius Black is the Godfather of Harry Potter," she pointed to Harry who was in a catatonic state, "he was sentenced to Azkaban for the murder of Peter Pettigrew and a group of muggles as well as telling Voldemort," Luna winced as she said the name knowing that if she didn't say the name Sere would be displeased and get her to say it anyway, "where the Potters were hiding. He escaped after 12 years and went looking for Harry and soon after went into hiding with few knowing his location."

Sere listened patiently to Luna absorbing the information, however it did not answer one of her important questions. "Is he guilty of these crimes?"

Luna shook her head, "No! He's innocent. He was framed by Peter when they made him the secret keeper of the Potters' whereabouts. He betrayed them and went and told Vol-his master where they were. Peter then staged to look like he was killed by Sirius making him take the down fall. But Sirius never committed any of those crimes."

Their conversation went unnoticed by others but Sere had by then gathered the necessary knowledge to carry out her plan.

"Luna I'll be back in a few minutes, okay?" Sere did not even wait to hear her answer, she just strode towards the arch with purposeful steps. People turned their heads and wondered at what she was doing. She walked straight into the Veil and disappearing from sight, they called out but no one was close enough to stop her. People once again stared in disbelief wanting to know why she would willingly walk into the arch from where she couldn't return.

Harry looked at Luna, wanting an answer as it seemed she knew this mysterious newcomer best. He was surprised that Luna didn't look upset instead she seemed to have look of understanding and awe on her face as if she knew something they did not. "Luna, who was that and why would she willingly go to her death?" he spoke, voice hoarse from his yelling. Others turned to Luna after hearing the question wanting to know the same.

She couldn't believe it! Why would her hero just walk to her death? She scrunched up her brow trying to think and then it hit her! 'Sere can't die that easily! She still got years to wait, she said so herself.' Her expression cleared at her revelation. 'That must mean she can get out! She has probably gone in there to save Sirius! Wow!' Luna was brought out of her thoughts by Harry asking the question she had just figured the answer to. "She is my friend and protector! And she has not walked to her death; she has gone to save Sirius!" Luna stated proudly. Harry and others looked at her strangely wondering how that woman could get out of the Veil.
