Whilst not specified, the loop is at the time of Queen Victoria's reign meaning it is between the years of 1837 to 1901.
Entrance to Devil's Acre Edit
Sharon takes people on tours of the loop, as he did Jacob Portman, Emma Bloom, and Addison MacHenry while they were looking for Caul and the rest of the peculiars in Library of Souls. Peculiars must travel though a tunnel in the Thames river to enter the loop.
Library of Souls Edit
Devil's Acre is the setting of most of the chapters in Library of Souls. It houses the Wights' Fortress.
