So the subject of Conquest is....
Battles of the Cyclops Cluster
Seige of Mezoa
Conquest of Manachea
Defence of Agathon
Events generally not covered by BL and a natural follow on from the Isstvan trilogy. The events that lead up to Vengeful Spirit with Horus using his legion and DG to cut a swathe across the Imperium.
Armies:
SoH
DG - no new units for these two, but new characters, warlord traits, configurations.
IH
Sallies, i.e. a shattered legions list to allow mixed forces
IF
Knights (a questing knights lists) and Titans
Mech - good and naughty
Solar Auxilia - full lists, warlord options etc. similar in extent to the Taghmata lists in Book 3
This book will provide rules for system wide campaign games.
The big new thing will be Relic Weapons from the Dark Age of Technology for all the legions, including some not yet covered such as WS and SWs :)
Release date is fairly loose - this calendar year, but possibly GDUK.
It's a stand alone rather than part of a trilogy.
