The morning sunlight barely reached the twisting tunnels of Mt. Moon, where Luke and his two Houndours had been training. The cave they had used for the past week felt familiar and safe, but the deeper tunnels ahead seemed almost alive, dark and winding. Luke tightened his backpack straps and called to his Pokémon.
"Stay close," he warned. "We're heading deeper into the mountain, but these paths are tricky."
At first, the trails were manageable. Stalactites hung from the ceilings like jagged teeth, and faint cracks let in shafts of sunlight. But soon, the tunnels split endlessly, turning in loops and dead ends. Luke realized quickly that he could easily lose track of their route. Every sound — dripping water, the echo of their footsteps, distant flutters — reminded him that Mt. Moon was full of hidden dangers.
Almost immediately, they encountered their first challenge. Zubat swooped silently from the shadows above. The male Houndour barked aggressively, tail flicking, and lunged forward, Ember blazing. The female Houndour, scarred eye glinting white, circled strategically, dodging the Zubat's swoops and following Luke's mental commands through his Dark-type aura. Ember struck true, and the Zubat fled, shrieking.
Hours later, a Golbat appeared, larger and stronger than any Zubat they had faced. Its wings beat with thunderous speed as it charged at them. Luke's heart pounded. "Houndours, work together! Hit it from different angles!"
The male attacked head-on, his flames distracting the Golbat, while the female struck from the side, dodging its fangs and slashing claws with precision. Each Ember and bite forced the Golbat backward, but it retaliated fiercely. Rocks crumbled from the ceiling as the battle escalated. Luke felt his aura pulsating — guiding, calming, and empowering his Pokémon simultaneously. The female Houndour's confidence grew with every strike, her fear disappearing completely as she began to match the male Houndour's boldness.
By the third day, both Houndours had adapted to the harsh cave environment. They moved with speed, skill, and coordination that Luke had never seen before. He felt his Dark-type powers growing as well, a steady hum of energy linking him to the two Pokémon he had.
Sleep came in short bursts, curled together in small alcoves, and meals were scarce but nutritious enough to keep their strength up. Luke marked time by battles and training, counting each encounter, each victory, each narrow escape. The Houndours' bond deepened; the male, aggressive yet protective, would check on the female after every intense encounter, while she responded with a soft growl or nuzzle, gradually revealing her proud, fiery personality.
