New Scenario 4: It's MAGIC!

Hello my children, I have a new scenario. This Scenario is special as it's going to cause a huge transition. Let's begin.
Your cousin Renaldo somehow found a pair of tickets to a magic show. They simply showed up on his desk one day, show he though "What the heck, I might as well see a free magic show." Seeing as your Renaldo's favorite cousin, he gladly takes you with him.
You both show up at a seemingly abandoned theater where this is supposed to take place. At first you two thought none were there, but you two begin to hear a storm of applause from the inside. It sounds like fun in there, so you guys eventually enter. A strange old man with a fox mask looks at you two and asks for the tickets. You two present him the tickets, and they burst into flames within his hand. “Please take a seat."
After entering the audience, you notice that everyone else in the audience is wearing fox mask. The only one who isn't is the magician running the show. Speaking of magicians.
As you walk down the steps in search for a seat, you hear the magician call out into the audience for an assistant. Your cousin immediately yells out "PICK ME, PICK ME!!!" She then looks at your cousin and says, “I choooooose...the guy right next to him." Suddenly two fox masked children grab your hands and pulls you to the stage. Before you know it, you’re stuffed into a box with the only audible sound being the magician. She tells the audience, "At the count of three, I will make this young chap DISAPPEAR. OOONE, twoooo,-"...That's weird, no three. You then push against the door and find yourself at the above image.
You then see a girl fighting off some strange monsters with a sword. She looks at you and says, “It’s about time I got some help." On the ground you find a short sword wedged between some rocks.
(By the way, the box is one way. You're not going back just yet.)
What do you say, what do you do?
