Ironthal is a tall human with facial features that are just slightly off from the norm to be noticable, but not quite enough to be thought of as disfigured. He is a craftsman in the golem district of Barithani.
His choice of craft seems to specialise in more intricate small designs of a variety of creatures, and rumour around the town tells that his larger works are very reliable, if not the most aesthetically pleasing.
Together with the party he ventured into The Sand Flats to find The World Spring in order to give help to his creation of a replacement arm for Sahalquiel. In addition with the aid of the research notes from “Chimera” provided by Graminea Malkovich he attempted to imbue the arm with power drawn from the celestial planes, and succeeded.
