DLC actually worth buying The best Total War: Warhammer DLC A Bretonnian force under the command of Joan of Arc-analogue Repanse de Lyonesse is available as a free DLC, as is a dwarf force under Thorek Ironbrow. The Empire (led by Huntsmarshal Wulfhart) return in The Hunter & the Beast, goblins (led by Grom the Paunch) are in The Warden & the Paunch, wood elves (led by the Sisters of Twilight) in The Twisted & the Twilight, and beastmen (led by Doombull Taurox) in The Silence & the Fury.
To confuse things, some subsets of the first game's factions are playable in the second game's Eye of the Vortex campaign with the right DLC. At the back you can see this army's lord, the ghost of a drowned opera singer who rides a giant crab.
