Orokin Derelict Assassination keys require five Lephantis Nav Coordinates to craft. These Coordinate orbs are found in all missions in the Orokin Derelict tilesets, dropping in addition to the regular Nav Coordinates. The Assassination mission itself drops Lephantis Nav Coordinates too, thus giving a chance to recover some of the used Coordinates. Lephantis Nav Coordinates do not drop from lockers but from breakable containers. They can not be traded between players.
As of Update 28.3 (2020-08-12), Lephantis Nav Coordinates were retired and were automatically converted into 
500 each.
