She founded an entire organization (The Path of the Twelve) dedicated to studying and learning and utilizing the gift, and a very many people were found. Most if not all of them went to Carteneau, where not all of them survived or made it out, and it's presumed the others stuck around in the rebuild and/or landed in the world of 2.0 after the timeskip.
Those folks are the ones who end up helping to staff at Waking Sands, and there's an event in the MSQ that deals with what becomes of them.
You can certainly have the Echo without being the Warrior of Light or even affiliated with them, though: There's no guarantee Minfy found everyone, after all.
