Skink. Shink. Fwoof.
You stand alone in the dark cave. All alone. No Creepers, no Skeletons, no Spiders.
Your flint and steel strikes against the obsidian and the portal flashes to life. Magenta and purple spirals flash infront of you. The swirls spin around elegantly and temptingly, as if to say, "Come with me. Don't be scared. I won't hurt you"
But you do not believe the portal's words. You've been through before. You won't be fooled again. Dressed head to toe in diamond armor, you are indestructible. You hold a diamond sword in your hand. It's enchanted. You clench it hard as you step up to the spirals.
You stand inside the portal. The sprials begin to consume your vision, until all you can see is magenta and purple. The heat of the portal climbs through your arms and legs and begins to crack into your heart. Even your full set of armor is no match for the tearing toll of it. The pain is unbearable.
You feel like you're falling to your knees, only you can't feel your legs. Your arms too. They've both gone so numb they feel like they're not there. Your heart beats faster and your brain feels like it's swelling up. Everything inside you screams with pain, like the noises you can here. in your ears.
Your teeth clench, your muscles singe, your vision fails, your heart pounds... and stops.
A minute later, you open your eyes again. You're lying on your back aching all over. Your head is stodgy and your thoughts bring pain, but you're alive. The fact that you're not dead is the only thing that moves you from your spot on the ground.
You lean forward towards your toes as your back screams out in pain. Hesitantly, you get to your feet, standing upright to see your surroundings.
You give a hefty sigh. Fire, lava, you're in the Nether.
