Yulya returns up the ladders to the southern end of the mushroom cave, She feels something important has been omitted from the Badger ring manual and confirms the effect with AshleyUh Cat be sure to use this ring only twice per day! Then give it to Alice!
The hole was fresh. I looked at it thoroughly. No signs of erosion or oxidation. There are 2 types of beam holes here. Ancient ones an fresh ones. The ancient ones don't fit the fresh rock we found on the road and the fresh ones here were made a day ago. Soo - Sherlock Alice concludes that there must have been 3 separate beaming events. One a long time ago here, one when we went back to Phandalin and one a day ago. Possibly to scare off that bear we encountered.
On top of that, the rock we found didn't look like it was lying out there for ages. Someone would have found it. Eventually people like Daran would have heard about it and wondered what magic caused this. And that dwarf would have recognized a rock from his own mine I'd say, even if drunk to the point of alcohol poisoning. So whoever makes those beams isn't a monster from this mine but someone who's capable of walking around outside in civilization. Probably a wizard unless we have guys with laser weapons here as I said.
Yulya is not entirely convinced.As far as I recall Sir Nundro said such rock would be encountered in the mine. Still it eludes me why someone would carry it to a road outside of Phandalin. Yet there is something even more concerning. Sir Nundro was unfamiliar with this type of damage. Meaning he had never been here. Nobody ever mentioned Mycoids either. How is this possible? Was this area sealed off? I see only two possibilities. Either the Rockseeker brothers are very unfamiliar with their mine - or they intentionally withheld this information from us...

We blocked the elevator. Unless any survivors climbed to another level or flat out teleported - I guess a beam wizard could, they should not have been able to leave this level. Weird.
You are correct, I had not considered this! Nobody should have been able to leave this level of the mine after we entered. However the elevator was up when we arrived. Someone must have survived and come up. I cannot really make sense of anything that is happening here. I will leave it to Ashley to send a wasp to investigate or not.
