Everything Discarded

Collect 4 salt crystals, 4 mushrooms and 4 samples of black sludge from the pipes.

The Dome project is the ideal scientific experiment, which appears to be completely isolated from the outside world! However, you cannot make it a hundred percent insulated, for there are things that we still need to remove − like waste, for instance. For a long time, we have been dumping them into the sewer system uncontrollably, but after a while, we have realized that in doing so, we have created a new experimentation ground, only beyond the Dome this time!
Yes, the discharge has influenced the flora and fauna of Xadagan in some way − and now we need to find out in which way exactly. Therefore, samples must be collected there as well. Get me the crystals formed of salt concentrates, some mushrooms and the measurements for the toxins that flow out of the pipes, {username}. I will analyze all of these.

Have you managed to collect anything?

Wonderful! It just takes a glance to see that an incomprehensible mutation has occurred... All right, now we need to study it in more detail. For instance, what happens if that black sludge were to be ingested... Do you want to try? Alright, if you don't, I'll offer it to our Xadaganian interns...
