Write a setting based on the most beautiful place you’ve ever seen.
My feet hurt, tied in thick boots that I've tripped over far too many times to count. The weather is hot, with the shorts and t-shirt I'm wearing feeling like concrete from the heat and sweat in the air. My hips stopped aching a long time ago from the back pack resting there, and instead are a dull throb as I follow the ground down a winding trail made of rocks and dirt and surrounded by trees. The edge of the trees is near and I'm not looking forward to stepping out into the direct sunlight, knowing that it'll only get hotter and we're not even halfway through the walking for today yet.
It's moments later when the trail leads us out from under the trees and I'm hit full on with the burning summer sun. Now there are no trees and the path cuts across a clearing with patches of tall grass and a large dip of liquid blue fire in the middle of it.
