In game - in the context of a long-running campaign I honestly wonder why Valachan is part of the Core at all. It really adds nothing, it's an insular domain with little cultural impact on the rest of the Core, and there's little reason to come here. Socially, the 'self-reliant woodman' trope is already all over Kartakass and Verbrek, so it doesn't add anything new or novel in terms of possible PC origins etc either (except as a source of dark-skinned PCs, and jeez, can't we do better than that?). There isn't really even any interesting side-quests or plot hooks here, everything is centred around the Baron. It's is a lot like Forlorn in that way, again, a domain designed for a single adventure. It'd be better as an island in the mists, to be honest. You could do a one-off weekend-in-hell type adventure here, using the (interesting) Felkovic's Cat artifact and trying to kill the baron, and being trapped here could actually be genuinely creepy and hard to survive given the Baron's myriad methods of spying (cats, nosferatu slaves, and the entire priesthood of Yutow is basically his spy network too). But that's kinda the only story that the place is good for, as written. The extra space in the Core (and pager count!) could have been much better used on different domain - Paridon would have been my choice, but Markovia, or relocating G'Henna somewhere to the desolate south-east of Hazlan, or something competely new like an underground dwarf domain would have added something new and unique to the Core, which Valachan just doesn't. If there's any Valachan enthusiasts out there who love the place, please let me know why I'm wrong.
