The Historical Remains is a static device in the Reclamation Algorithm game mode of Arknights.
Historical Remains can be found in some combat zones (excluding Raid interceptions) and causes the secret area in said zone to be revealed when destroyed. The Remains can only be damaged by units adjacent to it, like that of Tattered Pillars, but unlike other devices, it cannot be identified until attacked. Furthermore, the Remains appear similarly to background objects such as walls, which can make it difficult to be spotted.
