A sourced long-list of lore-friendly potential units for each faction.

Every source checked by sight.
Green = Already in TWW3
Blue = Oldhammer (1st - 3rd edition WHFB or related)
Orange = Core units
Pink = Newly added to existing list

WD = White Dwarf Magazine (UK version unless otherwise stated)
CJ = Citadel Journal
TC = Town Cryer
WFRP = Warhammer Fantasy Roleplay
FANM = Fanatic Magazine
HQ = Heroquest
AHQ = Advanced Heroquest
WHQ = Warhammer Quest
MoW = Man of War
WMM = Warmaster Magazine
AB = Army Book

My rules for inclusion: This is intended to be a comprehensive guide, but I won't include absolutely everything, particularly for factions that have a lot of choices. Top priority goes to stuff with WHFB rules, then WHFB lore only stuff, especially if it looks cool. Picks from other games (Dreadfleet, Heroquest etc.) if they are interesting and WFRP last. Nb. This is not a list of what I think CA will, or should, add to the game.

Note: The Monstrous Arcanum 8th ed. had rules that meant that every faction could take at least one of every monster described therein or in the Storm of Magic 8th ed. supplement. I have ignored this and treated only those listed as having Kinship as eligible.
