Being that we're in the "Adventures with Towers" club, it's important that I come by as a show of solidarity.
I appreciate the Sci-Fantasy here as it caught me by surprise! There's something about Fey, the forest and its health, and the presence of weird magic and artefacts that blends really well, no more so than here.
There's quite a bit of interconnectedness here and it seems to me that these few locations could very well keep adventurers busy while they figure out how to deal with the troubles at hand.
