Clouds roil overhead, the sun is hidden by the harbinger of a rainy deluge.
Tip, tip, Tiptiptiptiptip Rain begins to fall on metal armor. Saren, You feel it hit your scales dripping down your snout. The 7 Drow that march next to you look miserable. You shake your head, water droplets fall from your horns. Your hands are bound in magical chains dampening your connection to your god. The only solace you feel is the rain sent from Thor to torture your captors. Unfortunately, the same storm is also allowing them to travel during the day, speeding you on your way to who knows what foul end. A low roll of thunder rumbles in the distance.
You came to this island following strange and corrupted storms. Something is disrupting Thor's domain and you must find out what. As you approached what you believed to be the source of the corruption You heard vague stories about ruins in the jungle where you may find your answers. Before reaching the ruins you were set upon by a band of Drow. You defeated several before you were overwhelmed and captured. Now they lead you by a chain, you know that for now escape on your own would be impossible. The Drow behind you holds your weapons and gear. You march through a tropical jungle down an old muddy path, a raging river flows on your left, engorged by the sudden rain.
The leader halts and raises a fist. The entire company stops. Do you know Undercommon?
No: They whisper to each other in a harsh language you can't recognize. Yes: "Halt, The device detects something."
He holds what looks to be a compass in his hand and points to the trees in front of you. You blink the rain away and stare into the trees. For a moment you can not believe your eyes. Four well-armed individuals are ahead of you on the trail. A tiefling in full plate armor that obscures any notable features, a half-elf woman in robes, An armored woman who you swear is on fire even in the rain, and even more shocking than the ever-burning woman, a huge, pale man riding an even more massive flaming horse.
Magni, you have the highest passive perception, you turn and see on the road behind you a small company of drow in Black armor wearing Maroon cloaks. They have spotted you as well. What do you do?
The rain falls in sheets reducing visibility. (ranged attacks are made with disadvantage everyone is soaking wet, lightning does double damage, muddy ground difficult turrain)

You feel the voice more than hear it, "Why if it isn't the Hunters who have been following the trail I've laid out for them. So nice of you to join us. I'll be honest you did arrive earlier than I was expecting so forgive the state of the place. had you given me a few more days to prepare you would have been welcomed to a grand palace, but as it is you have arrived just in time to see the creation of the new world that you have been helping me create."
"where do you think the souls of the spirits and monsters you slay go? Back to thier own plane? Hardly, they are just as trapped in this plane as any other soul. But they need somewhere to go." He gestures behind him to the void, "Every monster youve slain, every one of my cultists youve killed, at least the ones since you foolishly took that maroon cloak, all of thier souls have been dragged here to the void, and they are a feast. Soon the table will be set and the dinner guests will arrive."
"The Hunters where the perfect orginization to help bring about the new era. They where more than willing to continue killing as theyve always done. Just add some magic Maroon cloaks to channel the dead souls and everything falls into place."
