In valley south of Sailen lives a healer called Nelyn Fethis. (house/tent and NPC would need creation). Nelyn Fethis furiously attacks anyone who approaches with his staff (The npc would have zero Luck and zero skill in Blunt weapon, so you could stand there indefinitly, minding your own business, while he tries to whack you. Also it would be required that he does not speak, because he’s mute, meaning some scripting work is required).
In Sailen, latest rumors indicate that Nelyn Fethis attacks everyone, but because he's had such terrible luck, he's never harmed anyone. The villagers have made it a habit to bring him food every so often (so the NPC's dwelling and surroundings should have evidence of plates and cups and silverware left.) If a guard is spoken to, they ask the player to bring Nelyn to the attention of the hetman Veradul Delvas. Veradul Delvas says Nelyn is a skilled healer who has helped many in their village and so they wish to help him. He asks the player to use a Calm Humanoid spell on Nelyn so they can speak to him without being attacked.
Once calmed, Nelyn passes the player notes and/or a journal explaining how he lost his voice, littered in curse words and anger about the villagers. A new woman had moved to town that Nelyn had believed was a witch. However, none of the townsfolk believed him, saying he was being paranoid, prejudiced, etc. He became angry enough to confront the woman in public, further making him into a laughing stock when she twisted his accusations to appear innocent. Later that night, the woman came to Nelyn under the guise of making amends, and instead cursed him to take his voice so that he would no longer spout lies about her. When Nelyn tried to get help from the townsfolk, they continued to believe he was just being difficult, some joking that he had yelled at the woman so much he had lost his voice, and Nelyn left the town in a rage.
When returned to, the hetman expresses regret about not dealing with the woma. He then says that in his younger years he used to traffic with Telvanni, and knows of a Telvanni mage who collects voices in little jars (an existing Telvanni NPC/house would need to be retrofitted to fit this). The hetman gives the player directions to this mage.
The Telvanni mage would say she could help and that she has already a certain voice in her mind, but that she needs the player to get some ingredients first. She gives the player a list of what she needs, about ten different “ingredients” of the usual weird things a Telvanni would want. After collecting everything on the list, the Telvanni has to be asked again if she'll make the voice using the ingredients. The Telvanni responds with "What? Are you stupid? This is my grocery list!" but then acedes and gives the player a jar named "Indoril Squeak" She says she used the voice of a famous Indoril theologian, though she forgot the name, because they anyways sound all the same.
After that you bring the voice back to Nelyn (some scripting propably needed here, to give Nelyn a "squeaky" Bosmer voice). Nelyn is thankful, and while he still doesn't quite forgive the villagers and chooses to stay away from the town, he agrees to heal any villagers who seek him out. He offers the player his staff as a reward (casts a healing spell or shield/sanctuary on strike perhaps?). When returned to, the hetman also thanks the player and gives them a gold reward.
