Story:
One day when Ethan was taking walk around Pangororia, he stumbled upon a new residential area that was under construction, with big buff pokemon lifting heavy materials and smaller ones for the areas that required more precision. He noticed the architecture for these new homes were a bit different from the pre-existing houses, sure they had most of the same materials but these new ones were built in such a way that gave off a different vibe, cooling in the arid weather yet still cozy. As Ethan walked outside the perimeter of the construction site admiring the progress, his aura eyes flickered on for a moment before deactivating just as quickly, making Ethan suspect another lost Ragtag nearby, though is confused since his aura eyes never flickered on and off like that before. So trying to work out the location of the ragtag as he walked, his aura eyes activated properly when he approached a house that was nearly complete, with just some decorations and other appliances needing to be installed. Just then, a blue bird swooped down from the sky, bringing the last few lights needed to finish the home. As Ethan noticed the ragtag mark on the bird’s wing, she accidentally bumped into Ethan when she was trying to land, though she and the lights were safe thanks to her massive poofy pamp, unfortunately Ethan happened to be under that pamp, though he didn’t mind at all. Once both of them got up, the blue bird introduced herself as Martlet, apologizing for landing on Ethan though he reassured her that he didn’t mind at all. Seeing Martlet almost done with the house, Ethan offered his assistance which Martlet was grateful for, with Ethan talking about the Ragtags and their situation along with Martlet sharing how she ended up in this world where she found a place to put her construction skills to good use. Once the house was complete, Ethan offered Martlet to join up with the other Ragtags which she happily accepted after she finished her quota for the day, as Ethan helped Martlet move some supplies to the next site.
