It's a fantasy role-playing game.

DM: You are Keyleth, a half-elf druid . You are the member of the famous group of adventurers. Previously,  The group of adventurers, Vox Machina, had found themselves in the Feywild, intent on discovering another one of the Vestiges of the Divergence, one of the many artifacts that they hope will aid them in their struggle against Thordak the Cinder King and the rest of the Chroma Conclave. They've defeated two of the members, three still remain, Thordak being the seeming powerhouse head of that troupe.
DM: All right. So as you ascend the side of the nearest tree, and it resembles Atreyu climbing up the tree in the Swamp of Sadness, as it's these large gnarled branches and bits of muck and dust falling off the sides, and the oil slick that is surrounding the base makes it difficult to find your handholds, but you do eventually get your way up into the tree over the next five to ten minutes. You were going to cast Commune with Nature, you said?
Player: Yes.
DM: All right. What do you want to ask?
Player: Do I sense a cancerous tree in the area?
DM: You're asking this of the tree? Or is this the land around you, right?
Player: Yeah, I'm not asking the tree.
DM: You concentrate for a second. You feel yourself link with the land, and it's a very jarring sensation. You're used to connecting with nature being this serene, wonderful experience. This is like plugging into a nightmare. Suddenly, your thought process is filled with this ever-drawn sense of dread. You feel this cold sensation fill your form, and you manage to get this information across, but it leaves this very hollow feeling in the center of your being. Feeling out, you do not sense a cancerous tree, but you do sense the strengthening presence of the source of this entire swamp's perpetual destitution and slow decay, further to the northwest of this.
Player: Northwest. Okay. So I can safely assume that the tree that they're heading towards is not cancerous.
DM: Correct.
