You enter a cavern lined with glowing fungi. Each one you touch emits a different pitch. If you play them in a certain order, a stone rolls away from the wall, revealing the way forward. How do you figure out the puzzle? What music will you make?

Lucifer's thoughts were still consumed by the words the face in the pyramid spoke. "Little Courser. Where is your Knight?", echoed in his mind day and night. He still had not the faintest idea what the face meant by that. He had no idea what a Knight was. He decided he would do his best to find out, even if it meant going to the Surface. He shuddered at that thought. He did not like the Surface, but he needed answers. Today was not the day for that though. 

Lucifer stood and shook the dust from his body. He watched as the dust swirled around him before resting on the ground. "Ashes to ashes, dust to dust. Someday that will probably be me.", he thought to himself, recalling the old Courser bones he'd seen in his travels. Wanting to take his mind off of the face's question, Lucifer decided he would venture out into the Dungeon. He had come across a puzzle he hadn't been able to solve in quite some time. 

Using his mental map he made his way down the Dungeon's corridors. He passed other adventurers who offered him a few friendly hellos. Lucifer said nothing. "Surface dwellers. I have nothing for you.", he thought as they continued past him. Lucifer walked for quite some time before reaching the cavern he was looking for. He was determined today would be the day he solved this puzzle. He had found the puzzle some months before when he first saw the glowing fungi. Intrigued, he touched each vibrant color, hearing a different musical pitch from each one. 

He looked at the stone. "Today is the day I move you from my path.", he stated with confidence. Luci turned to the fungi and began his tapping. He was methodical, tapping them in rhythm with a few songs he'd heard other Coursers hum as they passed by him. Nothing. He had not the faintest what order this could be. He had gone over and over the melodies, swapping pitches around, hoping something would happen. Nothing did. 

Lucifer stood, staring at the glowing variety of fungi. His mind raced with thoughts of possibilities, but concluded nothing. Feeling defeated, he plunked down beside an orange glowing mushroom. As Luci sat, his hip brushed against it. He heard the familiar pitch, and looked over at the mushroom. It's bright orange was almost mesmerising. Lucifer let out a sigh, he was flat out of ideas. "Maybe whatever is behind that stone holds the answer to this whole Knight thing.", he mumbled, glaring at the fungi laying on the ground.

With fresh ideas, Lucifer stood, brushing against the glowing mushroom. It produced it's pitch, and Luci came to a realization. His mind raced. Had he finally figured it out? He tapped his idea to the mushrooms. He held his breath as he heard a loud rumble. The ground beneath him began to quake. Dust overtook the cavern, causing Lucifer to cough. Once the dust settled, he looked at where the stone was, completely stunned. It had moved. Lucifer didn't know what to make of what was behind the stone. He was expecting something grand. A treasure trove was at the top of his list. Instead, there was nothing but more pathways. He couldn't help but wonder what they lead to. "I'm sure these parts of the Dungeon haven't been picked over," he stated. He shook the dust from his body and walked past the moved stone, intrigued to see what this part of his home had to offer him.
