During her visits to Rivendell, Inyahin was warned about the trolls of patrolling the roads of Trollshaws.
These giants, twice as tall as Inyahin, with skin as thick as wood, but there intelligence just as thick.
She had found troll tracks leading to an ancient abandoned watchtower, where the trolls had gathered in great numbers. She used trickery of song to distract and confuse them while she used her agility to out maneuver them and slice them up until they were dead.

Orchestrating the trolls, and directing their efforts, she found a servant, a Lesser Worm of Morgoth. Thankfully, Inyahin's previous experiences hunting dragon kind had now come to fruition and she dispatched this worm with ease.

On returning to the Library of Rivendell to record her deeds, she was awarded title Troll-Slayer, for her meritable actions.
