Trost District

The Trost District (トロスト区) is a town located on the south edge of Wall Rose. Because Trost is the town closest to the breach in Wall Maria, it is the town that most frequently comes under attack from Titans.

Characters from Trost include Tomas Wagner  and Jean Kirschtein.

Story
Five years after the fall of Wall Maria, the Colossal Titan appears again and breaks down the outer gate, causing the district to be invaded by Titans. However, the district is saved when Eren changes into his Titan form and plugs the hole using a large boulder.
