Sinderion

Sinderion is a male High Elf who is also a master alchemist. You can find him mixing potions and studying in The West Weald Inn in the city of Skingrad in Cyrodiil. Once you show him a sample of Nirnroot he becomes particular interested into this plant. If you bring him ten of the plants, he'll mix you up a special potion called Elixir of Exploration.
