Sinderion

Sinderion is a male 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 your help finding the Nirnroot, Sinderion is able to make the Elixir of Exploration via the Seeking Your Roots quest.

Alchemy training
Sinderion is the master Alchemy trainer. Upon reaching Expert level in Alchemy, Journeymen trainers refer the Hero of Kvatch to Sinderion. As a connoisseur of fine wines, Sinderion requires that one bottle of Tamika Vintage 399 and Surilie Brothers Vintage 399 be recovered before he agrees to impart his knowledge. He has no qualms about accepting stolen goods.

Wares
Sinderion serves as an alchemical merchant; given his low Mercantile skill, he is one of the easiest merchants to manipulate. But because his inventory never resets or regenerates, he keeps every item sold to him.

Interactions
Discovering a Nirnroot anywhere in Cyrodiil prompts the Hero to locate an alchemist to uncover the secrets of this odd plant. The alchemist then refers the Hero to Sinderion, who sends them on a mission to collect large quantities of the root. In return, he supplies them with strong potions.

Skyrim
His skeleton can be found inside Sinderion's Field Laboratory in Blackreach, where he went to investigate Crimson Nirnroot. He is found with three Dwarven Arrows in his back, leading one to believe that his murderer was the dwarven sphere outside his laboratory and not the falmer. (The Falmer do not use Dwarven Arrows). The true cause of his death is a mystery. When you try to loot his skeleton, it breaks. You can read or loot Sinderion's Field Journal from him. His Journal mentions a traveler who sought to collect Crimson Nirnroot. Reading his journal, or picking up a Crimson Nirnroot opens 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 you deliver the samples.
