===The Coming of Iron.===
Iron has previously been a scarce metal, found either as relics of the great Age [in various forms of steel] or as bloom iron, pounded into wrought iron or layered steel. The Powers had Many uses for Iron in the past and have mined all but the meanest sources.

Iron affects magic. A little makes it unstable, a lot disrupts it entirely.
Steel can be the same, but is sometimes a conduit for magic force instead. The hows and whys of this were known to the Powers, but that knowledge is yet to be regained.

I'd like to have a variety of different magic types in the game, based around systems from BRP, Legend and Runequest Three. Their relative rarity is up to you.
