Deep below Poketopia CIty, in an underground cavern…
Resides a city of Dark Elves called Black Haven. These elves used to live aboveground in the open, as did all elves, but went into hiding after colonists arrived to Zuunto about a hundred years ago. The human colonists attacked the elves indiscriminately, driving them into hiding. Now, one Dark Elf, Nifiken, has studied Dragons and their ancient kind from the scrolls kept in Black Haven's church. He stole one of the scrolls with writings of a mighty dragon imprisoned in the Lava Pit, a forbidden place deep in the caverns connected by underground cave networks.
Another Dark Elf, Illywyn, who thought she was abandoned at birth, watched the city of Black Haven from one of her many ledges on the outskirts of Black Haven. She had grown up in the Lava Pit, befriending a Torkoal and finding a magic sword that can transform into a quill. She has never directly interacted with anyone before. As she watched Black Haven this day, she saw an Dark Elf approaching her ledge.
Nifiken and his Cubone climbed up the ledge Illywyn was perched on. Illywyn retreated into the shadows of the tunnel behind her and tried to hide against the wall of the tunnel. Nifiken immediately saw her hiding and drew his bow, aiming it at her. They skirmished for a few minutes, Illywyn knocked to the ground with Nifiken's bow aimed at her.
The cave started rumbling, pebbles and rocks falling from the ceiling. They ran back toward Black Haven, and saw the entire cavern Black Haven was in starting to rumble as rocks and boulders fell from the roof and one crushed the town’s church.
They decided to go deeper into the cavern toward the Lava Pit, Nifiken's intended destination to locate the ancient Dragon, to escape the collapsing cavern. As they go deeper into the caves, Nifiken's Dragon scroll begins glowing red and heating up slightly. He also occasionally heard a hoarse, scratchy voice in his head, whispering "Come to me…" After many puzzles and shifting caverns, they entered a room filled with glowing mushrooms. Three Zubats screeched down the tunnel and attacked Illywyn and Nifiken. Nifiken fired two arrows from his bow, impaling one Zubat twice through the chest, instantly killing it. Illywyn palm-striked a second a Zubat, crushing its skull. Cubone smashed the third into the ground with its bone.
After Illywyn skins the Zubats and places their corpses in her cloak, they hear footsteps from ahead. Illywyn, Nifiken, and Cubone hid ein the shadows in the tunnel. The Dark Elf Elder from Black Haven walks into view, and Nifiken stepped out, recognizing him. The Elder appeared to be severely injured.
The Elder informs Rufus that while the cavern was collapsing, he found himself lost in passageways and tunnels that he had never seen before. Illywyn decides to reveal herself and steps out from the shadows. The Elder asks Nifiken and Illywyn to help him return to Black Haven. They agree to take him back once they reach the Lava Pit. The three elves traverse through the tunnels until they enter a room with three holes in the ground, leading to other rooms. Nifiken climbed down the left most hole into a small carved out room with a tiny, thin stream of water flowing down from what a hole in the wall. Metal bars covered the hole. The Dark Elves, having been underground for the past hundred years, don't have technology to make metal bars such as these. Peering through the metal bars, Nifiken discerns that the trickle of water is coming from some type of sewer. He is unable to brake the metal bars with his bow and arrow, so he climbs back up the hole with Illywyn's assitance. The rightmost hole has a pile of mangled Zubat carcasses directly below it, so they climb down the middle hole, leading into a pitch black corridor. As the three walk through the corridor, they hear skittering and scratching.
Illywyn notices tiny pieces of bone fragments littered on the ground. The three stride farther into the darkness until they reach a metal door. Illywyn recognizes the door as the entrance to a small room located next to the Lava Pit where Illywyn spends most of her time, as lava can be fairly hot. Before they can enter Illywyn's room, a small dark creature appears in front of it with gems for eyes and sharp claws. The Sableye grins and cackles, then leaps toward Nifiken. Illywyn, Cubone, and Nifiken proceed to battle the Sableye, protecting the Elder, until it retreats and phases through door into Illywyn's room. The group follows it inside, and Cubone smashes it with his bone. The Sableye hissed and phased through another door leading to the Lava Pit.
With the immediate threat of the Sableye gone, Nifiken gets a chance to look around the room. It's filled with advanced technology, computers, medical beds, and other various assortments that Nifiken nor the Elder have ever seen, and that Illywyn doesn't really know much about. Nifiken and the Elder, injured from the battle with the Sableye, decide to rest for a few hours while Illywyn keeps watch. When they awake, Nifiken notices a postcard of a beach on a stand near Illywyn. He recognizes the postcard, it being something that his little sister loved before she was kidnapped. He takes out a necklace with green gems he always carries with him that belonged to his sister. Illywyn vaguely recognizes the necklace. Nifiken realizes that this is his sister, but before they have time to capitalize on this realization, the Sableye phases through the door, climbing up the wall, hissing at them. Nifiken draws his bow, and Illywyn her sword. The Sableye leaps onto the Elder's head and plunges its claws into his eyes, ripping them out before Illywyn and Nifiken can react. Cubone charges toward the Sableye, who dodges away. Nifiken uses the dragon technique he learned from studying to swipe through the Sableye. It screeches in pain and turns invisible. As the Elder clutches his bleedig eye sockets, the Sableye reappears behind him and stabs a claw through the Elder's neck. Using this to their advantage, Illywyn, Nifiken, and Cubone attack the Sableye, who runs away and phases out of the room again.
The trio follow the Sableye outside into the Lava Pit cavern, where the Sableye is waiting. Nifiken charges it. The scroll he has in his possession is brighter and hotter than it ever has been, now that it's so close to the ancient Dragon. Nifiken channels the Dragon's power through him, and a translucent glowing dragon's tail grew from behind him. He swung his tail at the Sableye, knocking it back into the Lava Pit, where it disintegrates. Illywyn and Cubone join Nifiken at the edge of the Lava Pit. Illywyn's Torkoal approaches, happy to see Illywyn returned safely. Nifiken, however, hears the voice in his head much louder. It whispers to him, telling him to step in the lava, take the final step, trust me, come to me. Illywyn looks worriedly at him, and asks what's wrong. Nifiken, torn between the voice and his sister, steps out over the lava. Illywyn tries to grab him, but they both fall in. Cubone and Torkoal watch in shock as their partners sink below the lava. Illywyn's body disintegrates in the lava, but Nifiken's body remained intact. The voice spoke again, "Serve me, and gain all the great power you seek, or you will die in this lava." After hesitating, Nifiken accepts, and his body rises from the lava with glowing draconic energy encompassing his body, and two translucent dragon wings extending from either side of him. A giant Hydreigon rises behind Nifiken and fades away. Nifiken steps back onto the ground, and Illywyn's body begins to reform from the lava back on the ground.
The energy fades away from Nifiken, and he and Illywyn officially reunite. Illywyn asks where the ancient dragon is. Nifiken hears the voice again, "I am within you." They realize the Hydreigon, now using Nifiken as a vessel, had resurrected Illywyn from the lava, and had also been the one who kidnapped Illywyn as a child and brought her to the Lava Pit.
Nifiken and Illywyn return to Black Haven, and the Hydreigon inside Nifiken tells him that the cavern had collapsed because of an explosion caused by the humans aboveground. Nifiken and Illywyn decide to rally the Dark Elf people, and finally return to the surface to confront the humans, hoping to make peace, but prepared for war. Nifiken and Illywyn lead the people to the sewer entrance that they had discovered earlier, ready to return to the world above.
