Having stopped the flow of the toxin into the water supply, and with the cannister in his hands, he headed back to the lift. Nearest he could tell, there wasn't anyone else about. Whoever had done this had done it, left it, and probably wasn't coming back. At least, not coming back to the underground. It was entirely possible the person responsible was, at that very moment, in the same room as Katarine. A clever person, the type that could create illusions that remained even after they were gone, could easily hide among the common folk.
He rode the lift up, going past the main level and ascending to the third floor where she was. Stepping off the lift, he found himself soon looking in on a room full of, well, normal looking people.
"Curious," he said as he stepped into the room and showed the cannister to Katarine. "Whoever did this hid the dispenser inside of a Force Illusion that remained even though they did not."
Quickly surveying the room, he took note of everyone present and committed their faces to memory.
"Unwilling participants in the plot, I assume?"
Katarine Ryiah
