I've been thinking for a while about an interex (from the Horus Heresy books) codex. It could be quite interesting, and probably a bit like the eldar. I was thinking smething along the lines of:

WS BS S T W I A Ld Sv
Gleves 4 3 3 3 1 4 1 8 4+ Troop Choice

Equipment:Power weapons
Options:May take power spears (+1s and +1A)
May have a segeant (+1A, has power spear)
May be mounted on centaur bodies (count as cavalry, moved to Fast Attack)

WS BS S T W I A Ld Sv
Sagittars 3 4 3 3 1 4 1 8 4+ Troop Choice

Equipment:Power Bows
Options:May have a segeant (+1A)
May be mounted on centaur bodies (count as cavalry, moved to Fast Attack)

Power Bows: Range:18'' Strength:3 AP:3 Type:Rapid Fire



WS BS S T W I A Ld Sv
Kinebrach 3 3 4 4 1 3 2 7 5+ Elite Choice

Equipment:???(I dont know what weapons they use)
Options:May have a segeant (+1A)

I was thinking of giving the gleves and sagittars fleet as well.

Have Anatheme as a wargear option, that automatically wounds
Any help would be useful
