The Lost and The Damned.

This mod adds 3 'cultist' units for chaos and 6 'mortal' units to the vampire counts. These units are added to the pool of units available for rebel armies to spawn with.

Chaos:
Cultist Spearmen - expendable spear mob
Cultist Archers - expendable bow mob
Cultist Zealots - better-but-still-expendable 2h sword mob

Vamps:
Peasant Spears - expendable spear mob
Peasant Bowmen - expendable bow mob
Spearmen - regular spear & shield
Crossbowmen - regular crossbows
Trebuchet - not as flash as a cannon but hey, it still throws rocks
Thrall Lifeguards - elite mortal swordsmen

The 'chaos cultist' secretly plotting the downfall of order from within is a staple of warhammer fiction and is seemingly absent from the total war series - no longer! Also Sylvania isn't an undead wasteland, people live there and they've been known to fight for the vamps when called upon (as seen in that there recent bloodlines update, hey would ya look at that now).

New Model Empire - A major military reform act from Karl Franz
Reiksguard Foot - elite Empire units
Armoured Empire - Empire state troops with extra armor
Sensible rebels - rebel armies wont spawn with elite units
