Siobhan Abernant

The alchemist of the Golden Barge Company. She is a relatively short half elf with a has wide knowledge of herbs, alchemy, magic materials, and transmutation. She is somewhat standoffish towards those who don't appreciate the work she puts into her study, seeing as she is working in a largely male dominated field. She will immediately hold a grudge over anyone who belittles her skill set and ESPECIALLY if they refer to her as an herbalist.
She will provide the adventurers with healing potions, antitoxins, some light explosives including gunpowder, as well as rare metals, she will reward you with discounts if you provide her with rare materials or herbs. She was the only female student of the great alchemist Octavian the Transmuter.
