E4: 2nd Day, The First Assignment

The following morning Lute pluck headed back, dragon in tow.
 
After checking my traps, the rest of us headed out and it wasn't long before we found another black miniture dragon purched in the top of a tree. We managed to get it down and Roedyn captured it. That of course is about when it started to rain. Roedyn decided it was time to go back.
 
As we wandered deeper into the forest I began to feel an ominous presence around us and found webs in the trees. We left quickly. When the forest finally thined out we found ourselves in what Vesryn called the Fe Wild. The air there was very humid and the mist was thick. Giant mushrooms glowed in the distance.
 
Gossamer and Taegen immediately plastered themselves to poisonous glowing moss.
 
Vesryn seemed angry and I don't blame him… he didn't want any help taking care of them so I set out into the wilds to hopefully find a dragon so we could send at least one of them back to the academy.
 
I found a red miniature dragon hiding on the underside of a large mushroom. I kept an eye on it while I put together a makeshift Bola (turned out quite well, may keep) and captured it. When I came back to the group some time later I discovered everyone had managed to capture their own dragon.
 
I don't get it. Where'd they all come from?
 
...
 
At least it's over now.
 
...
 
We got back in record time (but not with a good record) only to discover that the classmates that had gone back earlier had gotten into some trouble… Chirp Is in the infirmary and the other two have detention.
 
It's not long until the other classmates come back with their dragons. My roommate, Nym'Ruil, though, was the last to arrive, with an escort.
 
What did he do?
