Jim and Toby have been brought to troll market since Jim got chosen by the amulet to be the first human troll hunter

you were a demon, a small one in fact, you have a wooden muzzle on your mouth and a horn on your head, you were just in the library, messing around with matches (blinky thought it was a good way of entertainment) and then you heard a commotion from central trollmarket

you run (waddle quickly) towards the crowd, you sqwadle through the crowd to see Blinky and Aaarrrggghhh with the new human trollhunter and draal screaming at him for being human and having the amulet
