Description
You have unlocked the capability of creating a teleport beacon to Founders' Falls.
How to Get
One obtains the Founders Falls Beacon supergroup badge by visiting all the Founders' Falls 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.
Location
The Founders Falls Beacon Badge location is (4781, 0, 4531), by the statue east of the Eden gate.
