This is an amazing mod that I've replayed countless times, I would be most thankful if you took the time to port it over to the new version (probably on the nexus tho, to be safe). Now they SAY some mods break when moved over, but most will work, so maybe it'd require very little work? Unless it breaks however, then it might mean more than before, I'm not sure.

And hey, I THINK there's new particle effects in Special Edition? Not sure, but might be fun to add some of those for more gloomy atmosphere.
Even if you don't, which is absolutely fine and understandable, I'll be replaying this one a bunch as we close in on Halloween just on regular Skyrim. Love this mod to bits ♥
