Lover's Betrayal

Chapter 1

In this steampunk era, you are the youngest of 3. You have a protective but awesome brother, and a unique older sister. You are 18. You have been fighting monsters with your older siblings and your 2 best friends, Robert and Aylin. Most of your monsters come through different portals. This one is no different. 

You have a fear of spiders, but you have 3 markings on your palm, that when you concentrate on, 3 different spiders appear. A small one (your personal favorite to keep company), a medium one, and a large one. You can control them, and tell them what to do. Now to the story...

----------------------------------------------------------------------------------------------
           It was a typical training day for you, your siblings and your friends. Out of nowhere, a portal opens right in the middle of your brothers lab/ training area. You stand up, brushing your (h/c) hair out of your face. You put your (favorite weapon) down and wait. A large skeleton mecha claws it way through the portal. You, being first in command, tell everybody to wait, listening to your instincts. They put down their weapons and follow your command.  Soon, the skeleton mecha puts down their weapon as well, and opens up, people stepping out of it. It's a boy, you thought, and his brother...possibly. Just act cool. "Hello, I am ___ ___. Who are you?", you question.
"I am Skull. This is Reaper, my little brother. I am 19. I have come from another world to seek refuge."

         "Refuge from what?", you inquire, concern on your face, your stance softening a little. You started to feel bad. If he came from the planet you thought of, this might be his last chance. You tried to be understanding. "I am seeking refuge from none other than Julia herself. I was once in her army, but I didn't believe in the same things she did. So I ran.", Skull explained. "Wow, that must have took guts to do something like that.", my brother admired. "It was hard, but this is my last chance. All of the other planets think I am a spy. Please give me a chance.", Skull begged. 

         All of the people look to me. "I have decided that, we will give you a second chance. But, you do anything suspicious, or do anything to make us think of you otherwise, we will tear you apart ourselves. Understood?", you state. He nods.
"Good. Now, here are the Conditions:

1) You will stay in my brothers spare room. If you are caught in anybody else's room without their permission,  you will be put under house arrest. 

2) You will eat with us at every meal.

3) You will train with us, battle with us, and our schedule will become yours.

4) And lastly, but most importantly, you will obey my every command, as I am in charge here. 

Do you agree to these terms and promise to abide by them?"

"I agree to these terms and I promise to abide by them.", Skull pledged.

"There is going to be a lot of tension here", Brother muttered to where only the other sibling could hear. She nods in agreement.
