I really like how Last Light articles tend to reference other stories, islands, groups, and concepts, it really makes it feel like a connected universe, so all your links were really fun to see! Additionally, the article itself does a pretty good job of endearing the reader to the Greeter so that the reveal has some oomph to it, but I will say the article as a whole doesn't have a huge amount of content. that makes sense for an introduction, but each article should still stand on its own. I think this one does that, but it could be better.
I'd love to see this continue as a series as well, a Last Light series in general would be super cool to see (especially by one of my favorite Last Light authors).
