So I always have a look at the galactic map when a new codex comes out, it's the best place to see the progression of the universe in my opinion.
As a Sisters player I always keep an eye on planets related to the Sisters of Battle. The Sisters have 2 main places of operation, Convent Prioris Terra and Convent Sanctorum on Ophelia VII.
Sacred Rose, Ebon Chalice and Argent Shroud are based on Terra and the Bloody Rose, Martyred Lady and Valorous Heart (chapter I use) are on Ophelia VII.
Now when looking at the Tyranid galactic map I noticed Ophelia VII couldn't be found. This is nothing special, it's not on all maps in the other codexes either but I did notice something. A hive tendril going to where it should be. So could Ophelia VII be under attack from the nids? This
GWs way of preparing a campaign of Sisters vs Nids (a Sisters vs Nid box was rumored last year if I remember correctly, then again Sisters vs Unknown (this rumors was just before the
GSC came out so could be them) rumor came out this year).
.....or are the Sisters going the same way as the Squats in being eaten by the nids? It would be the same as if Baal, Ultramar and Nocturne were to be eaten by the nids in term of damage to those chapters.
Personally I hope it's the beginning of a Sisters vs
GSC & Nids campaign. Old rumor did say Sisters vs Unknown faction and this rumor came out about 6 months before the
GSC were released. Then again as a Sisters played I've learnt we are at the bottom and mainly used as a testing ground for other factions (allot of the sisters rules released over the years have been given to other factions. Sisters were first to dual wield pistols, all armies now get Acts of Faith but they are called Stratagems etc. Read every Sisters codex and look at what changed from codex to codex and then search for the abilities that were removed in other codexes, especially
SM).
