And now they don't fit in a Land Raider with a character like they used to because for some reason, the Dark Mechanicum has sat on their hands/tendrils/manipulators for the last 10,000 years while the loyalists invent a bunch of new toys. Lame.
Technically, Celestine (and Verydian) should be Order of Our Martyred Lady if you want to get picky, but then, that would greatly annoy all the people who don't collect OoOML but bought her in the triumverate anyway. Apparently there's going to be faction specific differences for the various races, so wait until that's definately not a thing before you lose your cool - there could be a very good reason why everyone has <sub-faction> keywords.
