The moment I finally cracked the Surreptitious Seven-Star Seal Sundering and descended into the shadowy depths of The Chasm's Underground Mines, I knew I was in for an adventure unlike any other in Teyvat. 😮 The air hummed with ancient energy, and strange, glowing flora dotted the cavernous landscape. It was amidst this eerie beauty that I stumbled upon Khedive, an earnest researcher whose passion for fungi was as bright as the luminescent Starshrooms he sought. Little did I know that helping him would lead me on a fascinating, if slightly perilous, spelunking expedition deep into the mine's darkest corners. He needed a fellow enthusiast, or perhaps just a willing pack mule, to gather specimens for his 'Mycological Investigation'.

Khedive's eyes lit up when I mentioned I had a Starshroom tucked away in my inventory's Food section. 'Ah, excellent! You recognize their value!' he exclaimed, practically vibrating with excitement. 'These aren't just any mushrooms, you understand. Their bioluminescent properties are unique to this subterranean ecosystem! Could you possibly... gather eight more for my research? It's crucial!' His enthusiasm was infectious, though the task sounded deceptively simple. Finding eight more of these glowing yellow fungi meant venturing further into the treacherous, uncharted depths I'd only just begun to explore. I readily agreed, eager to aid his scholarly pursuit and uncover more of The Chasm's secrets.

Before setting off, I recalled Khedive mentioning the importance of being properly prepared. The 'Chasm Spelunkers' questline wasn't just a suggestion; navigating these mines effectively required the tools and knowledge it provided. Completing 'The Chasm Delvers' quests fully had been essential, finally revealing the complete map of the Underground Mines on my Adventurer's Handbook. 🗺️ More importantly, it had allowed me to upgrade my trusty Lumenstone Adjuvant Gadget. That little device, now pulsing with stronger light, was going to be my lifeline against the oppressive darkness and the insidious Dark Mud that clung to certain areas, sapping strength and vision. Without its purified light, finding the Starshrooms in the pitch-black recesses would have been nearly impossible.

Starshroom locations glow brightly in the dark recesses of The Glowing Narrows.

Armed with my map and upgraded Lumenstone, I plunged back into the gloom. Khedive's 'shining mushrooms,' the Starshrooms, preferred the darkest, most remote nooks. My first major stop was The Glowing Narrows. True to its name, the area had an ethereal, otherworldly feel, dominated by the colossal Giant Mushroom From Another Land. Xamaran, the sentient being residing there, watched my progress with silent curiosity as I carefully harvested the clusters of Starshrooms growing around its massive base and along the nearby cliffs. The ambient light here made them slightly easier to spot, their soft yellow glow a beacon in the perpetual twilight. I even picked up the beginnings of another intriguing World Quest whispered among the giant fungi.

The search wasn't confined to just The Glowing Narrows, however. Venturing into the Underground Waterway proved equally fruitful, though more challenging. Navigating the watery passages required careful footing. I found a significant cluster tucked away in the rightmost cave branching off the main water channel. It was damp, quiet, and felt strangely melancholic. Later, I learned this area was tied to the disappearance of an NPC named Uncle He, another hidden story woven into the fabric of The Chasm. The Starshrooms here seemed to grow in solitude, their light a lonely vigil in the echoing cave. Scouring these two primary areas yielded the eight precious fungi Khedive needed.

Here's a quick overview of the best Starshroom hunting grounds:

Location Key Features Ease of Access (with Lumenstone Adjuvant)
The Glowing Narrows Centered around the Giant Mushroom (Xamaran), abundant clusters, ambient light. ★★★★☆ (Easier to navigate, light helps)
Underground Waterway (Rightmost Cave) Damp cave environment, tied to Uncle He quest, isolated clusters. ★★★☆☆ (Requires careful navigation)
Other Remote Caverns Scattered singles or small groups, often in very dark corners. ★★☆☆☆ (Harder to find, more exploration)

Triumphant, though covered in a fine layer of Chasm dust and perhaps a bit of glowing spore residue, I hurried back to Khedive. His face broke into a wide grin as I presented the eight glowing Starshrooms. 'Magnificent! Truly magnificent work, Traveler!' he beamed, carefully taking the specimens. 'This will advance our understanding of The Chasm's unique bioluminescent flora immensely! Please, accept this as a token of the Akademiya's... and my personal... gratitude.'

Rewards for completing Khedive's fungal research, including the valuable Academia Recommendation Letter.

The rewards were certainly welcome:

  • 💫 150 Adventure EXP (Always needed to climb those ranks!)

  • 💎 20 Primogems (The universal currency of wishes!)

  • 💰 40,000 Mora (Never hurts to pad the wallet!)

But then Khedive added something unexpected. 'Ah, and since you've proven yourself such a capable researcher by also assisting with the Hydrological and Geological Investigations...' He produced a formal-looking letter sealed with an intricate insignia. '...this is an Academia Recommendation Letter. Should you ever find yourself in scholarly pursuits, or perhaps facing... difficulties... within the borders of Sumeru, present this. It may open doors, or at least, encourage a more favorable hearing.' He winked, a knowing glint in his eye. Back in 2022, Sumeru was just a distant promise on the horizon. Now, in 2025, having explored its rainforests and deserts, I can confirm that little letter did come in handy more than once when dealing with certain... overly bureaucratic scholars in the House of Daena! It was a reward that truly kept on giving, linking this early Chasm exploration directly to the Dendro Archon's realm.

Reflecting on that first deep dive into The Chasm's mines, the Mycological Investigation stands out. It wasn't the most epic battle or the grandest puzzle. It was a quieter quest, a journey into darkness guided by the soft glow of mushrooms. It taught me the value of preparation (thank you, upgraded Lumenstone!), the importance of exploring every nook and cranny, and how even helping a passionate mycologist could yield rewards – like Primogems and a surprisingly useful letter – that resonated far beyond the damp caves of The Chasm. It was a humble beginning to uncovering the grand, ancient secrets buried deep below Liyue, a testament to the fact that in Teyvat, adventure and discovery often bloom in the most unexpected places, even on the side of a glowing fungus. 🍄✨
