It’s great, Squidge! My personal taste would have been to start with:
“By Tilda’s twenty-sixth attempt to produce an illuminorb, Silviu’s patience…”
But I can’t say that would be better (in fact, it’s grammatically very awkward… so probably worse); it’s just how I would have done it. Otherwise, a cracking piece with a ton of world-building and backstory in there already.
