"Garden Positioning System", this
mineral device guides pioneers via
moogle magic to their Mog Gardens.
It glows with the iridescence of an
additional star for each day (Earth
time) the Green Thumb Moogle lays
his fuzzy paws upon it. As to what
significance the stars have, that
remains a moogle mystery.
Each Earth day that you enter your Mog Garden, you receive a message about a "single star" appearing on your GPS crystal. The stars currently do not have a use, and there is no way to check your total number of stars. In a future version update, these stars will be redeemable for some sort of reward.
