Teen Wolf:
I OWN NOTHING, GOOD DAY SIR!
They all sat there in the burnt house where the Hales used to live. The pack had gathered for some bonding time and when they were all preparing to eat they noticed something. All the werewolves could feel a change in the air but the druid was the one affected most. Seeing a member of their pack crouching in the corner trying to get away from something most began to question what was happening. That's when they noticed a distortion in the air. It looked like a small crack in the fabric of time.
"Guys, please tell me I'm not the only one seeing this."
"Shut up Stiles!"
As they all edged closer the portal spread and a Skeletal hand reaches out and pulls the gap wide open. The First thing they notices is the lack of heat in the room despite the fire in the corner then they notice a figure stepping out wielding the Iconic Death Scythe.
"Get back" Derek was shouting to the group as they prepared to fight the unknown threat.
"If you all want to carry on living I suggest you all sit in your chairs and shut the fuck up." The figure said with a voice like ice. The group slowly made their way to their seats and sat down all the while the figure began to fully emerge from the portal.
"What do you want with us?" Stiles asked, though they did not say it they all thought of that question.
"What I want is for you to sit there and listen before you start talking, boy." The figure responded although the sound came from the corners of the room. As the figure turned to them they noticed that the figure was quite tall.
"Can we at least know your name before you kill us?" Derek requested.
"Kill you! Ha, I'm not here to kill you, I'm here with a warning." It replied.
"It has come to my attention that in this part of your world that there has been the death of many innocents that should not be dying and that some of your neighbours are less than savoury people and are taking great pleasure in this. So my warning to you is that if this carries on then I will be forced to intervene and then you will all die. It has been many years since the last person invoked me into causing the mass death of a race but I am willing to do so despite the extra paper work."
"What do you mean mass death of a race?"
"Well, technically I didn't cause it my 4 horse men did." All of the people tried to move away from the character in the black but unfortunately they couldn't due to being sat down.
Then they heard a laugh and noticed that the figure was chuckling at them. "You should have seen your faces then, oh man that was funny. I forget you mortals are simple beings. I was joking about the horse men by the way."
Although they were still unnerved by this Scott lept towards the figure in hopes of pinning him only to be swatted away like a fly.
"Stop there mister." The figure turned and saw the argent family there. They all had different sorts of weaponry from sword to crossbows.
"Ahh yes the Argents. I have someone who wants to be reunited with you. She did a remarkable job for me in telling me all about the lycans/werewolves and hunter etc."
The portal that was gone opened up and unconscious Allison argent fell out.
"Allison!" all of them screamed at seeing their not long dead friend.
"So sorry for the deception but she was actually working for me and has been for a while and has done a very good job so when she 'died' I gave her life. She should be waking up now."
"Da…d" Allison managed to choke out before passing out.
