The Figdroids are from the Future Dimension. By the time of SOTS (which is a mere 2 months away from Rowana's chapters, so far) they had become agents working for Overbuild, not Leek Works. They showed up a bit after the Maelstrom Dimension attacked Future Leek Works, as Overbuild sent them to help. All I will say is Jaycee is not Jay.
The Darneu rocks mentioned were actually taken from the Forbidden Valley ones, as described in SOTS.
Nimbus City, also called the City of Nimbus, is a 305 square mile city first built for the Nimbus Republic's civilization reconstruction (CIVRC) project, and was the most populous metropolitan area in the system be-tween 3026 and 3038. Built over Nimbus Station's western sea, across the superbridge from the Race Place, the city's sea location was made possible by creating an artificial rock island for it to be built upon, with materi-als mined from the Darneu around Forbidden Valley. The city's plan and unique base construction method was envisioned by former-Assembly craftswoman Dedria Signer, a mindstorm for which you can be as-sured she has received many awards.
Nathaniel (intentionally spelled wrong) is Sergeant Ghost Mustache. :P Funny enough, there is an obscure line in SOTS that calls him "Thaddeus" too. As for them being nephews of the KOTOS, I hadn't thought of that, no. It could be a great coincidence that Thingguy's two characters are named similarly, but whatever isn't written is open for interpretation, so if nothing overwrites the possibility that they could be their nephews or in some other way related, it is possible.
"Weird, itâs almost like someone rewrote my memory of that" lol, meta humour
This is a reference to my rewrite of Full Circle, in which they originally killed the Darkitect, to have them not kill him.
Regarding Elistrans' rate of maturity, I did actually write a short story presenting this a short while back that you most likely did not see. You can read it here. https://talmidstories.fandom.com/wiki/Reasons In it the main character (guess who) thinks it has to do with sunlight but then again what does he know. :P
I wrote back to you in DMs but I'll respond to it again here, Ben is actually the progency of Ray and Mara, neither of whom seem to be Elistran, accordingly he isn't affected like Aiden and presumably Rowana are.
