Curate, connect, and discover
Nautilus is honestly the weirdest character in the series for me.
Like, he's moraly grey at best, seeming unfazed at killing people at the least, and I don't think enough people pay attention to him at all. Which is . . . Sad. I kind of hoped he would be a bigger villain, or at least more entertaining, than he was.
I mean, also, Webs confirmed himself that it was, at the very least, Nautilus' idea to lock the dragonets underground. (I wonder how much the guardians themselves hated it.)
Also, iirc, Cirrus literally said that he joined the ToP to get better at murder. So, that was a semi-regular occurance. Jeez.
