—It depends on what can be considered useful. —he lists the things he encountered. —There's a woolly giant, not aggressive. There's a tattoo artist, not aggressive, who wants to get to the surface. There's some kind of elf pretending to be sick, probably a mimic. There are sources with some kind of liquid, we have a sample for analysis. There's a poisonous field, and below it, near "our" village, there are living plants. Over there, at the top, are gates with this symbol and a strange guardian-creator. I didn't risk going further through the gates; he said there were some kind of sadistic trials there. And above the elf, something suspicious is sticking out of the ground. At the end, there's a house belonging to an ivy-artist, not aggressive, very perceptive. I think that's all.
