So many things have been retconned or changed in the last two decades and change that this setting has been around for... but for some reason certain names have proven immune to any sort of common sense.
Any name that is formed from two nouns smashed together is already facing an uphill battle to not sound ridiculous. "Deathfire" is just idiotic. It's right up there with the attempt to say that Lion El'Jonson, a name that served as a tribute to the poet Lionel Johnson (who wrote the poem "Dark Angel"), really means "The Lion, the Son of the Forest". I mean, I'm sure there's also a Calibanite out there whose last name is El'Peterson, which means "the Son of the Mountain" or whatever, right?
Jesus, just do away with those names. Change them. Pretend they never existed. Whatever.
LOL, your post is Reminded me of this...
Beyond that, I think beyond the fact that they have clearly distributed legions and Thematics between writers, it seems that the BL writers have too much works, or are too much in advance with the FW publication.
I feel that all those little meaningful stories brought by second wave authors are meant to be filler between the real great event of the HH.
ADB has confessed being a slow Writers, Dan Abnett is often workin on other works out of 40K and Graham MacNeill... is whatever you think of him...
Writing a whole novel is no small work, require a lot foretough if you want to make it at least half-right. Writing a whole series of this scale can be quite staggering.
Now put some executive meddling into the mix, and this can be a real nightmare....
EDIT : And Deathfire isn't that bad of a name... it's far worse : reminding me of the name Rob Liefeld gave to his characters in the 90's.
