You slide open the door, not quite sure what to expect from the plain, solid exterior... and step into another world. Clear plastic panels high above let in warm sunlight, illuminating a clear lake surrounded by golden grass. A wide, shallow stream runs from the lake, under a bridge, and winds away with a gurgle. Along the walls, there are entrances to more habitats and aviaries. You step forward, starting across the bridge - and are soaked by a golden Avka Felos lurking below. "Sebna! No splashing guests!" The scientist kneeling by the lake stands and bows. "My apologies. Welcome to Lab 53."
