This creature is truly fascinating.
Unlike anything previously documented by me or my predecessors. Its pin toothed maw lies at the surface nearly motionless like a predatory plant waiting for its unsuspecting prey. Based on the size of the visible portions of its physiology, my best estimations indicate that we are seeing no more than 10% of the creature. What lies beneath the surface may be truly massive and span the entirety of the Korvan Sands.
It seems insane to even ponder the idea, but it may be so large as to allow someone brave, or foolish enough, to tread freely inside the beast; depending on the biology of the creature's digestive tract, of course. Similar ventures had been attempted on the giant sand worms of Freanall Peninsula. Though those expeditions had proven markedly unsuccessful, this beast is many times larger than any worm on record.
This discovery is the culmination of my life's work. I cannot pass up such an opportunity, no matter how outlandish it may seem.
All the necessary preparations have been made. My initial observations of the beast indicate it is partially dormant during the hottest hours of the day. This is when we will attempt to make our descent into the gaping maw.
