There is a woman walking on a clearly marked path. Around a bend she is faced with a massive, unnatural fire. It was set maliciously with the purpose of consuming her, this intention has cause the fire to take on a life of its own. It roars when it notices her, fingers are reaching out to snatch her in. Rock walls are on either side of it. There is no going around it.
Keep your eyes on your path. You will be able to walk through it without being even being scorched, but you must walk swiftly and not ever stop. There will be many noises and sudden movements inside that will try to make you hesitate but with your eyes focused on your path and your mind intent on getting out you will make it through.
