|Services||Part of Seeking Your Roots, and Master Alchemy Trainer|
Sinderion is an Altmer and master alchemist residing in the basement of the West Weald Inn in Skingrad. Among his studies, he is working on a rare root, known as Nirnroot. With help gathering enough of the rare plant, Sinderion is able to craft equally rare and powerful potions.
Discovering a Nirnroot anywhere in Cyrodiil prompts the Hero of Kvatch to locate an Alchemist to uncover the secrets of this odd plant. Any alchemist will refer the Hero to Sinderion, who sends them on a mission to collect large quantities of the root. In return, he supplies them with varying levels of the potion Elixir of Exploration
Sinderion is the Master Alchemy trainer. Once the Hero reaches Expert level in Alchemy, Journeymen trainers refer them to Sinderion. As a connoisseur of fine wines, Sinderion requires one bottle of Tamika Vintage 399 and one of Surilie Brothers Vintage 399 before he agrees to impart his knowledge. He has no qualms about accepting stolen goods.
Sinderion serves as an alchemical merchant; given his low Mercantile skill, he is one of the more profitable merchants to trade with. However, his inventory never resets or regenerates, so he keeps every item sold to him.
His skeleton can be found inside Sinderion's Field Laboratory in Blackreach, where he went to investigate Crimson Nirnroot sometime after 4E 2. He is found with three dwarven arrows in his back, hinting that he was killed by a Dwarven Animatronic. Sinderion's Field Journal can be looted from him. It mentions a traveler who sought to collect Crimson Nirnroot. Reading his journal or picking up a Crimson Nirnroot begins the quest A Return To Your Roots, in which 30 samples of Crimson Nirnroot need to be collected. He has an apprentice, Avrusa Sarethi, to whom the samples are to be delivered.
