This can be a part of the "Soul Denied Heaven" plot if you want it to. It's meant to be a silly one-off.

You know the phrase "It'll be a cold day in Hell before that happens"? Or maybe "When Hell freezes over"? Well, what if I told you exactly that just happened? Yeah, you heard me. Apparently, Hell has its own winter. Who would've thought?

Anyways, intro time. You woke up and looked out the window, seeing the entire city covered in snow. You thought "Wait, it snows in Hell?" and head downstairs to check. As soon as you stepped out, you were hit in the face with a snowball. You looked over and saw Angel Dust cackling to himself.

Angel Dust: C'mon, sleepyhead! Get your shit on! It's not every year that Hell gets a snow day!

You look around and saw Niffty sliding down a hill on a sled with Baxter clung to her for dear life, Charlie and Vaggi making a snowman, Alastor watching them from the hotel's balcony, and even Sera, Emily, and Abel came from Heaven to spend the day with you and the gang.

Well, do you join in? And with who?
