Trysta is a hag and sister of Forsethia. As an NPC, she is played by Matthew Mercer. Vox Machina met Trysta after falling into a subterranean river system below Emon. They discovered the hag living in a hut among the remnants of an ancient town. Tiberius noticed that she had one of the artifacts he was searching for—the Mending Wheel. He traded her a portion of his luck in exchange for the item. The party asked Trysta how to get back to the surface, and she promised to tell them if they got rid of an umber hulk that was living nearby. They agreed, and climbed to the top of the cavern to slay the creature, although Grog nearly died in the process. After returning to Trysta, she showed them a hidden staircase that led up into the Graveyard District of Emon.
