Well... This day was interesting for you,to say the least.. You were experimenting with something with your magic along with your friend: [insert a friend of your oc here]. Both of you were using machines with your power to create a portal,both of you successfully made it, but... The portal was too powerful, and it sucked you inside,bringing you to a new universe,while the only thing you could hear was the sounds of wind passing through your ears,and the screams of fear of [insert a friend of your oc here] ... You saw you were falling,you looked around frantically in fear as you tried to see anything that could help to stick your landing,but before you could even react,your body hit the ground hard,magic shockwaves emitting from your body and creating a long explosion,which made trees,bushes and even animals get flung around and pushed around roughly,your vision was blurry as you groaned in pain and struggled to sit up,you managed to see an sign,that said..

Welcome to Green Hill!

Green Hill? {{user}},aka you,questioned in your mind as you put a hand on your head and started massaging softly,trying to calm down the aching headache as you heard some people,most likely a blue hedgehog named Sonic and his other friends which are called Tails and Knuckles,which.. Judging by how pained they sound like,it seems like the magic shockwave also got to them. You could hear some faint voices like:

Knuckles: "Dammit... My head.. What the heck was that?"

Tails: "I-... I don't know,what if it's Robotnick again..?"

Sonic: "Whatever it was.. Let's go check."

Oh no,what if they're dangerous? You couldn't risk trying to find friendly people,you didn't know anyone here. You quickly stood up as you hid behind some bushes and trees,the shadows covering and shadowing your entire frame as the trio of heroes looked around,clearly not knowing nor expecting a magic shockwave,you could hear one of them say again..*

Sonic: "This.. Is so weird.. Eggman never used magic before,much less this powerful,who could have caused this..?"

He said as he pointed at the grass,which had a lot of burn marks. It was dented, and it looked bad after the magic shockwave.

Knuckles: "Definitely,Eggman never used magic,just his damn robots.. The least he used was the Chaos Emerald,but this?"

Tails,ever the curious and smart one,decided to examine closely the burned grass while you were walking away quietly and hiding at the same time.

Tails: "This is nothing like I've seen before.."

[ ] Tails said with an hint of fascination,his tails swayed curiously behind him,you were still walking away,the voices slowly fading away as you tried to think of a way to get back to your universe,what would you do now?
