[Pool: 10/1 vs. 3/0]
The electricity-imbued nature in the lava tube had punished mistakes in their footing by painful but non-lethal voltage that raised the hair on their bodies but in the end didn't prevent them from reaching the bottom. Mr. Bravo had somehow avoided the contact with the fungus by some smart flying.
The underground river had been moving down through several small rapids, knee-high steps, that would suddenly end in a large grotto the size of an ancient cathedral. So far, the current had largely prevented the mycelium from spreading into its bed. Down here, where it poured out into stillness, no more. The cavernous space was well-lit, like from thousands pale cyan candles. In addition, the window-like opening on the other side of it brought to them both spot-moonlight and the roar of the crushing waves. The sobering scent of iodium and salts carried throughout as the sea must have poured out into the space from that opening on occasion.
The place awed and exulted. The majesty of it was hard to ignore even for a soul not bent on aesthetics.
And yet, this is where they found the scattered bodies. About a dozen of them littered the floor of their tomb, in various distances from where they stood, in various states of consumption and decomposition. However, the explanation why they were scattered like this didn't lie alone in the current carrying them from whence the group had approached. High above on the ceiling, where the mycelium was thickest, dozens of manta bids perched upside down, like bats, moving in soft undulation like drying laundry on light breeze. They seemed to be largely inert, slumbering, or given the pulsation at the end of their tales - charging? They rustled when the group entered the cave, but otherwise didn't move.
This couldn't be told of what was happening in the many pools dotting the floor of the grotto. Blue-laden, they swarmed with little mantas amid larger sack-like egg cases. Some of the bodies lay half-submerged in those pools, and were probably fed upon.
They *could* try to discern something about the bodies from where they stood, without risking entering the cave and facing whatever the reaction of life within it would be to their intrusion. But if they did want to intrude, a pathway of hexagonal steps where fungus didn't spread, probably because of crystallised sea salt had blocked its development, could be charted...
[Perception Hard with a Setback for observing from the spot, Stealth at Hard with A Challenge Die for trying to approach some bodies for closer examination. You can try different things and present your own ideas and I'll determine rolls for them. Non-stealthy hopping into the cave is also physically possible...]
