Seret is a neighborhood which can most easily be distinguished from Bevin by its lamps. Seret has moth lamps while Bevin has hand lamps. To those unfamiliar with the history of the restoration of the Cavern, Seret seems to be a variation on Bevin as opposed to a distinct type of neighborhood.
Seret is the second neighborhood opened by the DRC in their restoration efforts. While the first wave of Authorized Explorers were assigned to Bevin, later Authorized Explorers were assigned to Seret. Current explorers are assigned randomly to neighborhoods which are similar to either Bevin or Seret. While the Nexus reports that all neighborhoods are Bevin's, this is in fact inaccurate as some neighborhoods are similar in style to Seret.
