Also to clarify Followers of Light is our designation for all the civilizations that are in Galactic Federation of Light. This is the same, we are giving different names, our apologize for confusion. We are doing it because we need to point out what exactly things are, what are their goal and for which purpose they are made and as well like here which purpose does hierarchies follows.
And as we know Atlantis existed and it was sunk. It was one big city, it wasn't hi tech city as today, but there humans were living alongside with ETs from Galactic federation, not like all the times, only on occasions they were visiting, some basic technologies were given to atlanteans, like levitation with sound and lighting.
There were performed genetic experiments and augmentations of human bodies and nephilims ("half angels" - half humans) were made there. The problem arisen when nephilims along with atlanteans decided to become like ETs (like gods), to take their technologies and use it for themselves and to tel all the truth about them and so they were punished for this. Some atlanteans survived, and were allowed to live, but nephilims were destroyed completely, they were very unstable and in summary wanted to rule over everything. They were dimmed "unsuccessful experiment".
Since that time many cycles had passed, roughly speaking some 14000 cycles, in our knowledge this was also a time of great flood that touched all World. And Light Followers changed since that time as well. We will know detailed information soon enough, have patience!
Peace, Calm and Prosperity to You!
