(Was it out of place that the figure had clothing and hair and looked familiar?)
"Takuan, we need to have a group meeting to discuss our findings with everyone, to be sure that everyone is informed...especially about the hallucinations. Rianna and I just suffered them...I have a bruised face and Rianna felt the whip of a neuro-whip. It is very peculiar..."
(Could Rand perhaps find out if any of the other beings in this place suffer such things? Perhaps rove around and see if anyone is fighting imaginary creatures...)
(But, I am also guessing that the Dark Side makes it a tad too real for its own good, and brings up our worst fears...almost like the Fear Room on Dordellus...)
Bingo! It's EXACTLY like the fear room on Dordellus. This damn drug is more than just a halluceinogenic, it's a powerful brain stimulant. It probably doesn't do that much with normal people, but it hypes up your emotional states to the point where it hooks directly into your Dark side powers and triggers emotional extremes.
Except... two things. First, the dose is not controlled. Dordellus was set up medically. If anything, though, that probably means Dordellus was more extreme. But this will me more random. It is also continuous.
Secondly... they were oddly personal... the Dordellus effect raraly provoked conversation. This was almost abstract.
Oh, and unless you fell badly, you never got hurt by seeing anything on Dordellus- that would just be weird!
(of course, only the Kuylen bunch know thos, but they can fill you all in)
