I am looking into a LatD army and looking at it from a fluff perspective. As in they recruiting traitors for CSM inducting and such.
I love the word bearers idea but would like to some how incorporate it fluff wise into my Black Legion army (mostly because I like the black and gold color scheme). I was under the impression that Black Legion were just the head of the CSM (when they are organized) and are Abbaddon's personal legion.
In the LatD army the idea of Imp guard traitors following a CSM with a cursed croxious leading them, in a damned/fallen priest sort of way sounds pretty fluffy and fun. The traitors would be backed by equipment on loan from the black legion... rhinos and a defiler.
The idea is just that the word bearers taint thier beliefs and lur them to chaos to bolster the ranks of Abbaddon's crusades. It sounds loose, trying to figure out how it could work fluff wise. Sorry if it seems incoherent, I am a little out of it today.
