Droo's moons lore theories. Chapter 1: The lore surrounding Brigo.

We all have wondered how the three moons of Droo came to be. I want to give my view on it and hear what your point of view on the history of the three moons of Droo. This will be a three-part series on the lore surrounding the three moons of Droo.
This is my theory on Brigo: I would like to think that Brigo isn't made of Ice, but the surface is actually made out of about two or three-foot thick glass and crystals like honey quartz, making it have the brownish striped surface we know today. Before all of the glass was created on its surface, it used to be an ocean world that was beginning to develop plate tectonics, which would explain the ridges along its surface. The big crater on Brigos surface and no deformation opposite of the crater leads me to believe one of three things; 1. It was a super-volcano that blew billions of tons of material into space either interplanetary or in orbit around drew, causing Droo to have experienced a possibly month-long meteor shower, or the very least a two weeklong meteor shower due to some of the material falling back onto Brigo. The rest of the material was scattered around its orbit around Droo, meaning that Luna had gained some of the material along with Droo getting a very thin ring system around it. And the Atmosphere gradually was stripped away by an ever-weakening magnetosphere and once the atmosphere was stripped away enough to have the same over density of Cylero during its winter, the water on its surface boiled away or froze into glaciers near the poles and it was gradually covered up by dust and debris that circulated around the thin atmosphere. It maintained a weak magnetosphere due to tidal heating from being pulled on by Droo and Luna.
Theory 2 on why we don't see any surface uplift opposite of the crater if it is indeed an impact crater is if the surface of water took the brunt of the impact and slowed an impactor that I'll estimate to be about 15 kilometers in size before it reached the surface, when it reached the true surface, the water in the surrounding area along with the point of impact were all lifted up and the water flashed into steam and the impactor was absorbed into the core which caused the dynamo that was going to suddenly be halted. The heat from the impactor melted the silica rich rocks and sand, turning them into crystals and glass, the heat and shockwave from this event wrapped around the globe of Brigo 15 times over. Over a period of about a couple hundred thousand years, Brigo lost its atmosphere and any moisture it had in high amounts on the surface, meaning there is only water in shallow pools under the overlying two or three-foot thick glass and crystals that seal it away from the vacuum of space.
My third and Final Theory. This one is inspired by IntegratedSpaceSystems lore for Brigo and Droo. The Droods launched a powerful bomb with the equivalent TNT of the Fat Man atomic bomb dropped on Hiroshima multiplied 50 times over to cause that much destruction to the surface of Brigo which resulted in a month-long barrage of Debris and radioactive remnants to fall down to Droo, most of these burning up in the atmosphere while very few large chunk rocks either airburst over the surface of Droo or impacted the surface of Droo and caused widespread destruction in localized areas.
These are my thoughts on the lore history of Brigo. I would love to hear what you all have to say about your thoughts on Brigo, and let me know what you all think about the lore that I thought of if it is an accurate possibility or not.
