rmed with technology perfected before mankind ever rose from the primordial soup, the Necrons utilize weapons and strategies incomprehensible to all other races. Though the Warp is anathema to the metallic legions of the Necontyr and their undying masters, there are many other dimensions they can use, of which the other races are wholly ignorant. Using their mastery of space-time manipulation, the Necrons are able to create worlds within worlds, stable null fields and all manner of other exotic battlefield conditions. This is most evident in the use of Monoliths in a formation the Ordo Xenos has dubbed the "Phalanx." In this particular configuration, at certain pivotal places in the four-dimensional universe, the presence of a Phalanx emits a frequency waveform that distorts space-time and creates a powerful energy field known as a nodal grid. Within the confines of the shimmering nodal grid, the Necrons are all but impossible to destroy.
