So.... Was it just me, or did we get introduced to a few other Starborn characters in Battleground?  My reading of the conversation between Legend and Ethniu made it seem like he was starborn?

I'm curious about previous iterations? I'm still only through the first reading so I might have missed interpreted but something seems to have pinged that other starborn were at least referred to? If, as stated, every 666 years then previous years of that would have been ~1309, 643, -23, -689  using the timeline from references collection(https://www.paranetonline.com/index.php/topic,1592.0.html) 1300s was when Bob was bound and Drakul *might* have been born?  That's an interesting notion if that last round of starborn was Drakul.  Huh. Also makes sense why he knows a bunch more and that Black Court was doing that "stars and stones" stuff.

At this point, I think Mirror Mirror is going to have more stuff in common with the Flashpoint DC story than "Star Trek Evil Goatee".  It will be fun to see what kinds of wars and "things gone sideways" stuff can happen.

Given Harry's new (old?) abode, it makes things line up nicely for Little Chicago - but also if the comments about how the castle's wardings are similar to Demonreach's maybe there's some hints/help that can give Harry some ideas on time-travel or reality hopping.

I'm just irked it'd push the LTW(/River Shoulders now?) training stuff to maybe the book after?  Maybe an upcoming short story though. 

This is a great theory / topic thread so far.  I'm still parsing some of it.

However, I do have this question/thought though in relation to how the mortals spawn off new universes based on decisions (I couldn't find the exact wording, but I know it was based off of a WoJ).

However, we also know that (from Small Favor / copy-pasted from wiki) ....

A mortal's Name can change over time due to how their perception of themselves can change, whereas most supernatural being's Name is static and unchanging.

Therefore, is this GUCMT have a side effect of how True Names for mortals persist, or can the True Names of mortals be used by the higher ups as a way of "routing"  across the various universes (think like IP Addresses -- JB was an IT guy after all!)?

It's a bit of a side topic (/WAG-ish?)  but I thought it an intriguing concept.  I think it has other implications towards the plot of MM - but that's definitely a WAG.
