Tinkers hove long sought methods to help those soldiers haunted by their war experiences. The most methods attempt to erase the memories of those events altogether. Unfortunately, none have yet managed to achieve the desired degree of precision that would allow the removal of only selected memories. However, tinkers have managed to develop a machine that can erase the most recent memories of those it is used upon: the memory scrubber.

The memory scrubber is a chair attached to a large trunk full of machinery. The target of the device sits on the chair and places the device's helmet onto her head. The operator then choice of several settings; the device can attempt to scrub the target's memories of the last hours, days, weeks, months or years. Upon activation, targets report seeing flashes of light and hearing a buzzing sound, followed by a calming void. After one minute the process is complete. If the process was successful, the target will be unable to remember any part or aspect of the period erased. Use of memory scrubbers has occasionally caused some trouble when it has resulted in the loss of crucial information. Yet thus far, no tinker has created a machine to recover erased memories.
