And now I'm having images of Adeptus Mechanicus finding an STC of salt-shaker-shaped infantry power-suits and outfitting a good deal of the Imperial Guard with them. The suits are called Daltonian Armatures of Extermination (named after John Dalton in relation to his work on atomic theory and the tiny nuclear reactors that power the suits). So, of course, the Guardsmen shorten the name to "Dal-X", which gets corrupted into "Daleks". Oh, and the Mechanicus is wary of altering the designs in STCs, so they leave the part where the weapons only work when the operator of the suit yells "EXTERMINATE" at regular intervals, which ends up being rough on the operators' throats. Flash-forward a couple of millennia and a couple of freak warp-storms, and a bunch of horribly mutated Dalek Guardsmen end up in a brand new universe, having completely lost their sense of humanity but gained greatly increased intellect. All that remains of their former culture are a few cheerful Imperial teachings such as: "The Emperor asks only that you hate", "The dissident invites only retribution", "Suffer not the xenos to live", "Kill the alien, burn the heretic, purge the unclean", "To admit defeat is to blaspheme against the Emperor", etc. They no longer remember who this "Emperor" is but think of him as the source of all wisdom. Eventually they get in a big fight with the Time Lords.
