In the far future, among the endless chaos of the 42nd millennium, war has raged days of yore. In these grim and dour times, a battered collection of survivors flee from an ill-fated Imperial campaign, only to find themselves hauled from their reality to to crash upon the realm of Gensokyo. This stark realm will test oaths and faith as what it bears is alien to these tempered souls.

Peace.
