There's an epic battle taking place all over the surface of Mirrodin. Karn is somewhere below, trapped by the Phyrexians, half-mad under the influence of their contagious oil. Our heroes Koth, Elspeth Tirel, and Venser are...walking. A lot. There are no details about the actual conflict that forms the backbone of an incredibly intriguing story (all these are found in the card game's promotional material, thanks to the creative team). The "battles" are incredibly repetitive and not remotely exciting, and it's patently obvious that if the three planeswalkers had spent the entire novel on the surface fighting the war rather than walking aimlessly through the poorly described interior of the plane (I think the author mentioned it smelled like rotting meat once or twice...or forty seven times), then the Mirrans might have actually WON the war. There is absolutely no character development whatsoever, the leaders of the Mirran resistance (namely Ezuri) are depicted as slimy, ambitious jerks profiteering for power, and the only significant events of the entire book take place within the last five pages. There is no climax; there aren't even any Phyrexians guarding Karn, the would-be Father of Machines, despite his obvious importance to their cause. I guarantee that the player's guides from Scars of Mirrodin, Mirrodin Besieged, and New Phyrexia Fat Packs are more informative and interesting than this poorly conceived and poorly edited waste of print.
