Sheogorad Alchemist, Jiron Hlervan comes to you from just outside of Morrowind in Skyrim, a criminal with a past.  He is here now, living his life in quiet and solitude on this small Island.  He has a few plants, pets, and is a master of alchemy.  Jiron has around 31 new drinks to sell you, some are quite powerful, but come at and appropriate price.  He does travel to Khuul and other locations to retrieve the ingredients he needs occassionally, other than that, you will always find him right here, on Big Head's Island.
