Mootland is a province introduced in Total War: Warhammer II (during the The Empire Undivided Update) for the Mortal Empires campaign.
Prior to that, The Moot was a settlement in the province of Stirland (province).
Mootland is an imperial province with rich fertile soil, inhabited mostly by Halflings - a short race related to humans. More interested in comfort than warfare, Halflings are known for their fine produce, good cooking and large appetites. Outside of the Moot, humans often stereotype Halflings as cowardly, gluttonous, dishonest and stupid.
In the game, The Moot starts the game owned by Stirland.
