From the Goddess‘s hand comes this power, this golden core…
Thanks to this power, she penetrates Rover's chest, forming a Tacet Mark (where it is possible to catch a glimpse of the cosmos, among other things) and seems to pick up something inside…
Five golden cores emerge from his chest!
during the descent towards Solaris-3 the cores leave Rover's hand
and when he descend from the Etheric Sea we can see that they go somewhere in the world.
If we assume that these golden cores are the Remnant what can we say now?
Extract from Comprehensive Mirror for Historians:
“The Remnant is a pure and complete form of frequency energy whose recorded information can exist stably in some form beyond time and space.”
CBT2 Reverberation description:
“During the Waveworn Phenomenon, matter, information, and energy are all reduced to the frequency of vibration, and the frequency energy form that remains and continues to decay afterwards is the "Reverberation". According to research observations, once the Remnant decays, it will become a Reverberation, and this process is irreversible.”
