Yeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeet! Some interesting stuff. I thought the spaceship might be a Star Trek one after your described it for some reason and the more I continued the more I thought it might really be one. And then its captain is actually Talmid... wait no. If I recall correctly and you haven't changed it, that's not the first name of the Fleet Captain we know of. Yeah he's Edric while the one here is Edwin. Firstly, that makes some sense considering that we are a few years earlier than the Talmid Show's adventures. Either he's some relative of Edric (and now I want to see the family tree again; lol what the hecc is this https://talmidstories.fandom.com/wiki/Talmid_(Family) ?) that managed to travel to another universe before even thedude or anyone Edric knows, himself included; or he's from a separate Star Trek dimension.
The materialisation of intricate objects like that is interesting, but considering the description of Nexus Minifigures being that they're like mini Nexuses and the Nexus can materialise stuff like that, it shouldn't surprise me that much. Though I wonder what sort of people like her Edwin might know from his own dimension. That's another sign it's a separate dimension, because I don't think there's any such people that I know of in the Talmid Show dimension other than dimensional invaders maybe.
But yeah I wonder what Edwin and the Spectre Borg are going to bring into the story and how the former is gonna work together with Kate (who's starting to discover her powers, too). Wonder if the fact that he's interdimensionally related to Aiden is going to have any significance. Also, what Nathaniel is supposed to be doing here. Now that you mentioned a Nexus Force outpost, I suppose it's the NF that sent him, but that's not very specific.
Overall a pretty interesting chapter that brings hype for the future. I enjoyed it quite much. Also the elements of LU sprinkled here and there are fun and nostalgic to see.
