Xandar Fountain Puzzle
In the central plaza of Xandar is a squarish fountain, with a gold plate out front.
Melt it to solve 1/4th of the fountain. Find the next gold plate in a pool slightly outward and Old Westward.
Then in a corner of dry pool, coreward.
And the last one in the green strip near Nova HQ.
Return to the fountain to claim your brick.
