Ducktales Trollhunter human reader insert

You know the series of Ducktales. You know Trollhunters. Good.

After becoming human again, Jim was no longer the Trollhunter. Douxie decided to remake the amulet so Jim could be the Trollhunter again. Two problems, there's no need for the Trollhunter anymore, and after making it, the amulet chose someone else. Y/N L/N, a random person in Arcadia. They already know all about the Trolls and Aliens and so on in the town, and Douxie decided to use his magic to send the Trollhunter to a place where help is needed.
He forgot to mention it's an entirely different dimension where humans don't exist. Can Y/N survive in a world where she's likely to be experimented on like the government in her dimension did to goblins, trolls, and aliens?

Please be patient with me, I'm used to writing female readers. If I have put "she" instead of "they", please tell me.
