You have unlocked the capability of creating a teleport beacon to Kings Row.
How to Get
One obtains the Kings Row Beacon supergroup badge by visiting all the Kings Row exploration badge locations while in supergroup mode.
Note that visiting these locations while not in supergroup mode will not advance towards earning this beacon badge, even though it will earn the personal exploration badge for that marker. Previously earned exploration badges will count towards the beacon if revisited in supergroup mode. You will not see any reward until last exploration badge unlocks the teleport beacon when revisiting.
The Kings Row Beacon Badge location is (-1333, -43.2, 663), on the grass west of the Yellow Line.
