Thanks for reading and I appreciate the constructive feedback!
The location numbering is definitely confusing and in a future edit I plan to reorder them. That was just the way I ordered them when writing the module to help my brain group them together (like conceptualizing where the little stream flows and so on). Concerning Goblins, when you get your TROIKA book and read the entry on Goblins, their presence may make more sense. Goblins, in Troika canon, are the "vanguards of civilization", continually expanding their inter-dimensional labyrinth and expanding the multiverse while simultaneously being pests. They occasionally get stranded during these forays and "become feral".
