Adventures in Eberron
Little is known about the Iron Brotherhood – only one member has been seen before, and only by Victor. He or she keeps zir face hidden but speaks in a straightforward and open manner. When last seen, ze appeared after The Searchers met Molric, a racist dwarf that hates warforged.
The Iron Brotherhood instructed Victor to keep his eyes out for how meat-people treat warforged, and that ze would be back in touch soon.
