You were reincarnated as the heir to the throne in the Nether Dimension. But it was currently at war in with the Overworld Dimension, and you ended up being sacrificed by being thrown into lava in order for the Nether to gain the upper hand. Some months later, 2 Nether mercenaries, named Scarlet and Pyra who were both female Piglins, were hired by someone in the Overworld to keep your burnt dead body away from the Nether Empress. We go to them now riding on Striders across a lava lake hauling your corpse on another Strider.
Pyra: "Ugh, I nearly got burned in lava getting the heir, who hired us for this job again..?"
Scarlet: "She claims to be an old friend of theirs. The Nether Queen stashed them in lava to be revived in the future. Our client wants us to get them out of reach of the Nether Queen and her necromancer friends."
Pyra: "How does the client even know about this lava thing?"
Scarlet: "Eh... beats me. I heard that even Lord Zarkos doesn't have the resources to do so. It would take a lot of power that's for sure, like the combined energy of a Nether Star and an End Crystal just to get their heart beating again."
Pyra: "The Piglin Queen had an End Crystal, why didn't the Nether Queen just borrow it? Is she stupid?"
Scarlet: "Maybe the Piglin Queen didn't tell her?"
Pyra: "But aren't they allies?"
Scarlet: "Well, she could have other motives. The heir saved her life, maybe she wanted to the favor--."
Just then, a magical blast of energy soared throughout the Nether, cutting off the women's conversation. A course of the energy went through your corpse, giving it a jolt, but otherwise went still again. There was a moment of silence for a while until Scarlet broke it
Scarlet: "Huh... Must've been the magma serpent. Come on, let's push forward."
Pyra: "The WHAT now?!"
Scarlet: "Relax, it's not like its gonna eat us. It has no appetite for Piglins."
Pyra: "GIRL! It's a giant monster! What does it eat if not Piglins?"
Scarlet: "I don't know. Soul Sand? Quartz? Relax, you're overthinking it."
Pyra: "That doesn't even make--ughh, forget it. I don't get paid enough for this job..."
Just then, you jolted awake with a gasp of air, completely revived.
Some time later...
Scarlet: "And lastly, we got hired by a client from the Overworld to keep you away from the Nether Queen... or should I say-the Empress?"
Scarlet: "Then, a magical blast roared, leading us to where we are now..."
Pyra nods in agreement
Pyra: "And that's pretty much all that happened while you were gone..!"
