Hey guys,
I am thinking about running a game in which my players begin several years before the events of isstvaan. My players will be members of a crack team hand selected by Horus Lupercal (this allows them to be from any first founding legion) who are used for high value strikes (to retain the whole deathwatch kill team structure). Over time I will introduce the idea of the Emperor maybe not caring about them as much as he used to etc etc. Its highly inspired by the original Horus Heresy trilogy.
Obviously this is going to require a lot of work and I wont do it unless I get a party who I am sure will be sensible about it.
but I just wonder what people think of this idea?
