The Order: 1886 is set in an alternate history London, where an old order of knights keep all of the world safe from half breed monsters, who are a combination of animal and man.
In the game's history, around the seventh or eighth centuries a small number of humans took on bestial traits. The majority of humans feared these half breeds and war broke out. Despite the humans outnumbering the half breeds, their animal strength gave them the upper hand in centuries of conflict.
