His main competition in town is the Order armorer, who has recently acquired some Mahakaman anvils remarkably similar to those confiscated by the City Guard from Malcolm's own smithy. But if things seem bleak in Chapter II, they are even bleaker in Chapter III where his workplace is pretty much reduced to a firepit.
In Chapter V, it seems Malcolm has relocated to the makeshift forge in Old Vizima to help the Scoia'tael cause. It is he who makes the Scoia'tael (elven) variant of the Raven's armor for Geralt. Although he is not specifically identified, the conversation he has with Geralt would only make sense if it was Malcolm.
- Incidentally the name Stein means stone in German.
