Now, I do think that this region MIGHT be unfinished? As Rusty here mentioned, there's a lot of rooms that don't go anywhere and the platforming seems to be impossible in some parts (though take that with a grain of salt, i might just be bad fkjnjghf). It also looks like the upper parts might connect to underhang in the future, which could be cool. In any case, this is a really impressive region, highly recommend.

WHAT A LOVELY MOD!! a lot of the rooms are genuinely impressive and have some effects and terrain that I really haven't seen done before. The added connection between Shaded and Sub is lovely and feels fitting, seeing as they both include ancient religious sites, and again, the visuals in this region are STUNNING! And the unique shelters were an amazing touch too, felt really cozy

The music is amazing too, had the threat theme stuck in my head for a little while after playing. And the music pearl actually took me off guard a little, but it's SO GOOD! I made a little video showcasing the pearl just for me to listen to, but if you'd rather I take it down, do let me know and I'll be happy to!

what room in shaded

Connects to Subterranean & Shaded Citadel

what region does this connect railway to?

Really like this region so far! The aesthetic fits the regions it connects to, while there are also cool subregions that look great and quite unique. Finding a path through the debris can be a bit awkward at times, but I think that fits, and it makes for some more interesting platforming.

I do have to say that the path between the two gates is very linear and quite short. And the sections that split off from the linear path, while a really cool find, don’t really seem to lead anywhere. I don’t know whether this is intentional, or you intend to expand on those parts?

Overall, I really like the region. Definitely recommend others to try it out!
