So far I have Russ and his Wolves, two 10-man squads of Space Wolf Veterans, a 15 man squad of Grey Slayers, the character that came with Prospero, a unit of Scouts and a squad of terminators for the Rout.
For the Thousand Sons I have a Castellax, although one of the standard ones, two squads of Veterans, I just finished the second squad of tactical marines, a unit of terminators, a unit of scarab occult terminators, a unit of spire guard, a contemptor and Ahriman.
I also have some Legio Custodes but only the one squad. I need to get more of those guys and get a proper start on that order. Probably my next Forge World order.
We've only played a few games set on Prospero itself and we haven't managed to get into a campaign proper yet. I've been sort of waiting on some of the Forge World stuff that has come out recently and by that time I got distracted by Dark Imperium and 40K stuff, like the Genestealer Cultists.
I'd like to have a proper campaign running by crimbo and get a game in for it once a month or so. I'd like to have my Space Wolves dreadnought finished by then as well as another unit of Grey Slayers.
One game I'm eyeing up doing in preparation for that would be the fight in the western edge of the Rout's advance using SW:A pitting Thousand Sons Ammitara Occult vs. Vyka Fenryka in Scout armour, where the Ammitara can use the various teleportation paths to move around the battlefield and Rout are being constantly out maneuvered.
But first I'll probably finish of my Primaris marines when I get some more, hopefully next week.
