Base

Base is a faction initially founded by Mike Walters, Anne, Edgar, Marissa Ng, and Hunter Jeremiah Hartley. In subsequent timelines, Mike has also recruited Charlie, Chance, and Shadow. It is currently led by Hunter, after a wide-sweeping correction made it so that Base was founded under his guidance.

Base's access to spacetime technology is highly limited, but they do have some Calculators and have used them to perform experiments. They are in contact with and often take orders from — or receive corrections from – future versions of Base. In particular, corrections have often come through the Mikes living in Latvia.

Base operates out of a house rented by Anne "in the middle of nowhere," though likely in proximity to O.V.E.R. This house has served as the residence for several Base members, including Anne, Edgar, and Mike, though the latter two have since moved back into O.V.E.R. in order to replace OVEdgar and O.V.E.R. Mike. Ten years in the future, this house no longer exists, though it is unclear whether this has always been the case or if it is because of the transfer of command to Hunter.
