What is it about?
The Legend of Heroes: Trails of Cold Steel is the sixth instalment in the main Trails series and the first instalment of the Erebonia arc, set in Erebonia.
The game follows Rean Schwarzer, who finds himself part of Thors Military Academy's brand new Class VII, an experimental course of study in which the otherwise-segregated nobles and commoners are forced to intermix. Over the next six months, Rean and his classmates find themselves lodged deep within Erebonia's complex political landscape as it begins to fracture over worsening class conflict, discovering hidden agendas and terrorist plots that threaten to erupt chaos across the whole empire.
