Marco Tierra is a Terrier of the Sharks, walking out of every drowned hall slightly more useful than walking in. Pups near the overgrown stadium rim say Marco Tierra once stayed up all night arguing with a metal flower from the satellite field, and won. Bakers slip Marco Tierra the fresher biscuits near the rooftop kennels and pretend they did not. Marco Tierra believes the drowned places still hold pieces of the first Pixel Pup memory, and that belief is hard to shake. Shark Club Member: Shark Club pups are the descendants of rescue divers and deep scouts, the brave water ghosts of the Pixel Pups. The shark hat began long ago as a water training aid for pups bred to enter flooded rescue zones, and the fin still marks the ones willing to enter what others fear. They explore drowned subway tunnels, coastal towers, the lower mall after rain season, and any place the old world left underwater, recovering relics that may explain where Canis Sapien came from and why the sky once burned white. They smell faintly of pond moss, old coins, and victory, paint waves on their dens, wear teeth on their collars, and have each others backs in deep places the way only swimmers can. The Shark Club is one of the two largest sub factions among the Pixel Pups, and Finn is the corgi who first put a paw on the K N L door and made the fin mean something more than a joke.
