Perpetum Machinarium

Source Planes: Creation, Law

The eternal clock, ruled over by Primus, the machine of existence. The Modrons make their home here. While the eternal war of good versus evil rages on over their heads, the creatures fight another one - order versus chaos. Most of them invade the Everchanging Limbo and seek to introduce structure and form in a place where there isn't any. The plane is visited by the Mechagnomes of Quadropolis.
